Abstract

Here proposed is a modified molybdosilicic acid method for the determination of silicate in sea water.A suitable acidity is used to obtain higher sensitivity and stability.At this acidity,the salt effect coefficient is lowered to about 4%.To eliminate the calibration of salt effect,artificial sea water is applied.In order to simplify the method and to diminish the work on ship,the mixed reagent is introduced.The precision and accuracy of the modified method is satisfactory.The standard solution of silicate prepared by this method is stable within one year.
