Total Organic Matter

Total organic material or Total Organic Matter (TOM) illustrates the total organic matter content of a body of water comprising dissolved organic matter, suspended (particulate) and colloids. TOM analysis principle nearly equal to the principle of COD analysis is based on the fact that almost all of the organic material can be oxidized by using compounds of potassium permanganate or ...

Water pH Measurement

pH or acidity is used to express the degree of acidity (or alkalinity owned by a solution. That meant “acidity” is the concentration of hydrogen ions (H +) in water solvent. The pH values ​​ranging from 0 to 14. A solution is said to be neutral if it has pH = 7. The pH value> 7 indicates alkaline solution properties, ...

Way Winkler Titration Method

Dissolved oxygen is the number of mg / l of oxygen gas dissolved in water. dissolved oxygen in water can be derived from the process of photosynthesis by phytoplankton and aquatic plants or on the diffusion of air. Dissolved oxygen levels can be determined by titration and electronic measuring instrument DO meter. Winkler way based on two oxidation – reduction ...

Free Carbon Dioxide and Chemical Oxygen

Problem-free analyzed carbon dioxide that is in the form of carbon dioxide gas contained in water. The content of CO 2-free in pure water at a pressure of 1 atm and a temperature of 25 ° C is about 0.4 ppm. CO 2 in water is obtained from the air of the diffusion process and the results of the process ...

Total Hardness

Water hardness is the content of certain minerals in the water, generally ionkalsium (Ca) and magnesium (Mg) in the form garamkarbonat. Hard water or hard water is water that has a high mineral content, while soft water is water with a low mineral levels. In addition to calcium and magnesium ions, can also cause the hardness of the other metal ...
