High molecular weight water soluble nanoscale polymers (HWP) have different functional functions and different applications. For the first time in livestock, we applied GDP in feeding ruminants to increase their dairy and meat productivity. When developing an innovative feed additive based on nanosized anionic polymers, it is necessary to study their properties, for this purpose it is necessary to determine the presence of these polymers in aqueous solutions. Currently, there are several basic methods for determining the concentration of HWP in water. However, they have significant disadvantages, including complexity of execution, duration of the process, use of aggressive reagents, necessity to use expensive equipment. Our rapid method of quantifying anionic HWP is simple, accurate and inexpensive. The method is based on the flocculating properties of polymers. The method envisages preparation of basic and auxiliary solutions of golden ochre pigment and saturated solution of mixture of sodium and potassium chloride salts, determination of time of gold ochre pigment settling in idle test and in analysed solutions. Formulas for calculation of ochre sedimentation rate and polymer concentration are given. The method can be used in the concentration range of anionic polymers 0.0001 0.5 mg/ml. The express method is intended for specialists of chemical laboratories of industrial and agricultural enterprises, scientific and medical institutions.
