AMMONIUM ION ANALYSIS METHOD USING POLAROGRAPHY METHOD IN EXISTING ZINC ION LIQUID

摘要

The ammonium ion analyzing method is used to analyze the ammonium ion within the solution containing a large amount of Zn ion by using a polarography method using hexamethylenetetramine which is produced by the reaction of the ammonium ion with formaldehyde. The ammonium ion analyzing method comprises the steps of: mixing in a ratio of 1:1 a buffering solution of acetate of 0.4 mol with the formaldehyde of 37% to form a supporting electrolytic solution; adding EDTA(Ethylenediaminetetraacetic acid) in the mixed solution to extrude the interference of the Zn ion.
