Tekstur Tanah Berdasarkan Volume

Penetapan tekstur tanah dengan menggunakan persen volume dapat dilakukan dengan lebih sederhana dibandingkan dengan metode hidrometer. Prinsip penetapan berdasarkan persen volume ini juga berdasarkan pada kecepatan pengendapan. Dimana fraksi yang kasar atau pasir akan mengendap lebih awal (1 meniut) dan kemudian diikuti oleh fraksi debu sekitar 2 jam, dan sisanya adalah fraksi liat yang akan mengendap sekitar 48 jam kemudian. ...

Measurement of Dissolved Oxygen Meter

The working principle of this tool is to use the DO meter or probe oxygen electrode consists of a cathode and an anode immersed in an electrolyte solution. DO meter on the instrument, typically using a cathode of silver (Ag) and an anode lead (Pb). Overall, this electrode is coated with a plastic membrane that is semi-permeable to oxygen. The ...

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 ...
