[Possible use of a colorimetric method for determining silicon levels in animal tissues].
The colorimetric method was studied for the possibility to be used for the quantitative determination of silicon in the phosphorus-rich tissues. The formation of the blue silicomolybdic complex was used to colour the test solutions. It is shown that a considerable interaction between Si and P resulting in distortion of the analysis occurs in solutions containing more than 10 micrograms/ml of P. The concentration of P less than 10 micrograms/ml does not prevent from silicon determination, that evidences for the expedience of maximum dilution of biological fluids before their examination by the colorimetric method.
