Visual-colorimetric determination includes sampling (and its preparation in the analysis of soils and soils), adding test components. The concentration of the component is determined by comparing the color of the solution with the color chart included.
Color, Turbidity, Dissolved oxygen, Permanganate index, pH, NH4+, NO3–, NO2–, PO43-, F–, Cl–, SO42-, SO32-, S2-, I–, Active chlorine (free and total), Ozone , Si, B, Fe, Mn, Cr, Zn, Ag, Cu, Ni, Al, Co, Phenolic index, Formaldehyde
Ammonium nitrogen, Nitrate nitrogen, Mobile phosphorus, Potassium, Humic acids, Exchangeable acidity, pH, mobile forms of Manganese, Zinc, Copper, Molybdenum, Total heavy metals, Hydrazines, Chlorides
Titrimetric determination includes sampling (and its preparation for the analysis of soils and soils), adding test components, one of the solutions is added dropwise, counting drops, until the color of the solution changes. The concentration of the component is calculated by multiplying the number of drops by the given coefficient.
