pH measurement: Six technical tips
The pH value is one of the most important and therefore also one of the most frequently measured quantities in analytical chemistry. Sometimes, a simple pH test strip is sufficient for making a rapid check; precise pH meters are, however, required whenever accurate measuring results are needed. Such a pH meter is available in nearly every laboratory and is generally ready for use at a moment's ...

How can I detect Nitrite in meat
In Europe many meat products like ham and smoked pork chop are cured. Curing is a process to preserve meat and sausages by addition of common salt. The meat develops a typical curing taste and becomes red in color. This process is important to avoid a grey coloration and a growth of microorganisms. However the reaction of nitrite with amino acids, can cause the formation of carcinogenic ...

Accuracy, precision, usability, and cost of portable silver test methods for ceramic filter factories
Locally manufactured ceramic water filters are one effective household drinking water treatment technology. During manufacturing, silver nanoparticles or silver nitrate are applied to prevent microbiological growth within the filter and increase bacterial removal efficacy. Currently, there is no recommendation for manufacturers to test silver concentrations of application solutions or ...

On Some Issues in Triaxial Extension Tests
Results of triaxial extension tests on dry sand are presented. Special attention is paid to the factors influencing the results in triaxial extension tests. It is found that factors such as accuracy of the axial force measurement, axial force carried by the rubber membrane surrounding the specimen, gravity, and inhomogeneous deformation have a much larger influence on the results in triaxial ...

How can I measure temporary and permanent water hardness?
Hard water is water with high levels of dissolved minerals, and usually occurs in areas where limestone and chalk are common. These minerals can be divided into two types, and so hardness is often considered in two categories – permanent and temporary water hardness. So how can we measure water hardness? Can we measure temporary and permanent hardness separately? Types of Water Hardness ...

Cylindrical Expansion Test for Tensile Properties of Geotextiles
This technical note describes a new apparatus and testing procedure to perform rapid quality control and assessment of the design parameters of geosynthetic materials. The cylindrical expansion test (CET) is based on the principles of the extension of a geosynthetic specimen wrapped around the surface of an expanding thin-wall cylinder. The parametric study conducted on two nonwoven polyolefin ...

The Toxicity Identification of Inorganic Toxicants in Real World Samples
Abstract :The toxicity of a sediment pore water and an effluent was characterized using Toxicity Identification Evaluation (TIE) procedures. Both samples exhibited acute toxicity to the freshwater crustaceanThamnocephalus platyurus. The TIE approach was conducted using an enlarged battery of fractionation tests. Toxicity of the pore water sample was removed or reduced significantly by the cation ...

Aerobic co-treatment of landfill leachate and domestic wastewater – are slowly biodegradable organics removed or simply diluted?
This study investigated the co-treatment of landfill leachate/domestic wastewater in bench-scale activated sludge (AS) reactors to determine whether the slowly biodegradable organic matter (SBOM) was removed rather than diluted. The AS reactors were loaded with mixtures of raw leachate and leachate that was pretreated by air stripping. The tested volumetric ratios were 0%, 0.2%, ...

What should you do if you spot chemical runoff?
Chemical runoff is a major source of water pollution. It occurs when there is more water than land can absorb. In extreme cases, the excess flow of liquid can cause irreversible damage to everything in its path. However, with regular monitoring, the worst case scenario can be prevented. Natural and human-made chemical runoff To spot chemical runoff it is important to know what to look for. ...
