  • Life Among The Heavy Metals

    Authors in scientific and applied works interpret the meaning of the concept "heavy metals" in different ways. Today, they include more than 40 chemical elements with an atomic mass of more than 50 atomic units. An important role in the determination of heavy metals is played by the following conditions: their high toxicity in relatively low concentrations, and the ability to bioaccumulation. ...

  • How to investigate mercury in the oceans?

    Mercury is a highly toxic metal that affects the environment and can endanger people's health, as a powerful neurotoxin. The combustion of coal, waste and fuel are releasing hundreds of tons of heavy metal into the atmosphere annually, and its sediment enters to soil and water. Mercury measurements are part of the EU project "Global Mercury Observation System". The long-term goal of this ...

  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...

  • Some notes about Fats and Oils in Food and about FAME and FAMEWAX

    In Europe, the last transition periods named in REGULATION (EU) No 1169/2011 on the provision of food information to consumers are running out on Dec. 13th, 2016. Since then, a nutrition declaration is mandatory for nearly all packed food in Europe, wherein the amounts of fat, saturates, carbohydrate, sugars, protein and salt have to be included. The content of the mandatory nutrition ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Removal of Hg(II) from aqueous solution using sodium humate as heavy metal capturing agent

    An environmental friendly and economic natural biopolymer-sodium humate (HA-Na) was used to capture Hg(II) from aqueous solutions, and the trapped Hg(II) (HA-Na-Hg) was then removed by aluminium coagulation. The best Hg(II) capturing performance (90.60%) was observed under the following conditions: initial pH of 7.0, coagulation pH of 6.0, HA-Na dosage of 5.0 g L−1, ...

  • Solvent-Free Synthesis of c-Axis Oriented ZSM-5 Crystals with Enhanced Methanol to Gasoline Catalytic Activity

    ZSM-5 crystals with controllable c-axis length were successfully synthesized through a one-pot solvent-free route, with urea as an additive. X-ray diffraction patterns (XRD) show that the prepared samples exhibit high crystallinity. N2 adsorption–desorption isotherms and mercury intrusion porosimetry (MIP) analysis together with TEM observations indicate that micro-, meso-, and ...
