Popis: | An indirect voltammetric method for the determination of silicate at the ppm level was developed. The method is based or. the D.C. polarographic current measurement of molybdate ion formed by the decomposition of 12-molybdophosphoric and 12-molybdosilicic acids. After separation of the heteropoly acids by the liquid-liquid extraction technique, the heteropoly acids are decomposed with a basic buffer. After adjusting the solution to the proper conditions, the current measurement is made at the dropping mercury electrode. |
