A quick guide to oil analysis for engine test applications

Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

Heavy Metals Analysis

Correct measurement results are a prerequisite for compliance with limit values, which are always specified as total metals. Heavy metals such as copper, nickel, zinc, etc. can be quickly and reliably determined in aqueous samples with the help of the LANGE cuvette tests. Matrix factors (e.g. interference ions, colour, turbidities, etc.) may have a negative impact on themeasurement and cause ...

Analysis of wastewater for metals using ICP-OES

The analysis of wastewater for trace metal contamination is an important step in ensuring human and environmental health. Wastewater is regulated differently in different countries, but the goal is to minimize the pollution introduced into natural waterways. In the U.S., the Environmental Protection Agency (EPA), in conjunction with the states, negotiates a discharge permit through the National ...

Are nanosized or dissolved metals more toxic in the environment? A meta‐analysis

Recently, much has been written about the utmost urgency of elaborating the regulations for engineered nanomaterials. It is required from both politicians, to protect people from potentially adverse effects of nanomaterials, and from industry representatives, so that they can prove to have carefully and cautiously produced their nanoproducts and avoid potential court proceedings. However, ...

Analysis of trace metals in drinking water with the optima 7000 DV ICP-OES

With the development of mining, smelting and other industrial activities, heavy metals are increasingly being found in freshwater sources which can pose severe threats to human and environmental health. Pollution by heavy metals (such as Cd, Pb, etc.) not only affects the productivity of crops, but also the quality of the atmosphere as well as water bodies and threatens the health and life of ...

Oil and metal price movements and BRIC macro–economy: an empirical analysis

Brazil, Russia, India, and China are the four fastest growing economies to emerge at the dawn of the new century. Concisely referred to as BRIC, the growth of these states has transferred sources of wealth and capital. To fuel such rising economies requires resources. In particular, food, construction materials, and energy are necessary to sustain BRIC growth. This paper will ultimately examine ...

Evaluation of Sampling and Field-Filtration Methods for the Analysis of Trace Metals in Ground Water

Selected ground water sampling and field-filtration methods were evaluated to determine their effects on field parameters and trace metal concentrations in samples collected under several types of field conditions. The study focused on conditions where traditional approaches may produce turbid samples, which often leads to filtration of suspended particles from the sample before laboratory ...

X-ray fluorescence analysis of additives and wear metals in used lubricating oils

The determination of metal concentrations in lubricating oils is a very important diagnostic development. Such analysis dates back over 50 years, when one of its earliest uses was to assess engine oil from trains. Today, the analysis of both new and used lubricating oils, as well as the monitoring of trends in the metal concentrations and additives they contain, has become an essential control. ...

Retention of heavy metals by stormwater filtration systems: breakthrough analysis

Biofiltration systems are widely used to mitigate the impacts of stormwater on receiving waters, however their long-term capacity to retain heavy metals has not previously been assessed. Accelerated-dosing laboratory experiments were used to assess the likelihood of breakthrough occurring for three different types of soil-based filter media that are commonly used in stormwater biofilters. In all ...

Equilibrium analysis for heavy metal cation removal using cement kiln dust

Ion exchange, reverse osmosis, and chemical precipitation have been investigated extensively for heavy metal uptake. However, they are deemed too expensive to meet stringent effluent characteristics. In this study, cement kiln dust (CKD) was examined for the removal of target heavy metals. Adsorption studies in completely mixed batch reactors were used to generate equilibrium pH adsorption ...

Mining Metals Solution Treatability

Integrated Engineers, Inc. conducted a treatability test on water containing metals in solution from a mining company’s analysis labs. Initial pH was below 2, so it was adjusted to 6.5 to 7.5 using caustic. This lowers the solubility of the metals, and helps the Floccin to work better. The Floccin-1105 worked well at a dosage of 2.1 grams/ 1,000 ml of wastewater (treatment dosage of .9 lbs. of ...

Mercury Analysis

Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

New ways for Metal Recycling

REWAVE XRF 3-way-sorting in innovative “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

Ground Water Sampling for Metal Analyses

The Regional Superfund Ground Water Forum is a group of ground-water scientists, representing EPA’s Regional Superfund Offices, organized to exchange up-to-date information related to ground-water remediation at Superfund sites. Filtration of ground-water samples for metals analysis is an issue identified by the Forum as a concern of Superfund decisionmakers. Inconsistency in EPA Superfund ...

Analysis of the heavy metal pollutants in sediment samples collected from Thane Creek of Maharashtra, India

The wetland of Thane Creek, located at Thane, Mumbai, India, has attracted much attention of environmental biologists over the last few decades, as this creek has been subjected to a lot of pollution from the Asia's biggest Thane–Belapur industrial complex located at the south of Mumbai harbour along the west coast of India. This paper advocates ecological studies with special reference to the ...

Cluster analysis approach to identify metal sources in bottom sediments of Sultan Marsh canals, Turkey

The aim of this study was to determine heavy metal contents of the bottom sediments in Sultan Marsh water canals and drainage canals and possible sources of those heavy metals. The dendogram based on cluster analyses of the elements revealed two distinct groups of metals. There was a strong, positive correlation between some elements and their possible sources. Fe, Mn, Al, Ti, Cu, Zn and Cd ...
