Description

Methods for analyzing zinc borates: B2O3 determination in the presence of zinc ions and determination of zinc in the presence of borates are developed. Distributing effect of zinc in alcalometrical determination of B2O3 is removed using either its binding cationite KU-2 in H-form in hydrochloric acid medium or using complexone 3 masking. In the first case the results are underestimated, in the second one - are overestimated. When analyzing Zn the complexonometrical titration with sodium teraborate is carried out. Borate ions don't affect the accuracy of determination. Zinc borate samples of 0.1-0.15 g in dimesion are recommended according to the method suggested
