除藻剂B─329的极谱法测定

Determination of B-329 by polarography

以极谱法研究了Ｂ—３２９的电反应和测定方法．发现在０．１ｍｏｌ／Ｌ的ＨＣＩＯ４介质中，Ｂ－３２９在－１．１５Ｖ（ｖ．ｓＳＣＥ）有一灵敏的还原波，波高与Ｂ－３２９浓度在８．０×１０－５～１．０×１０－３ｍｏｌ／Ｌ之间有良好的线性关系．以此条件为基础建立了极谱分析方法．

A method is described for detcrmination of B-329 by polarography. In 0.1 mol/L HClO4 medium, the B-329 shows a cathodie polarography wave at 1.15V(v. s SCE). The polarographic currents is direetly proportional to the concentration of the B-329 in the range of 8. 0×105-1. 0 ×10 3mol/L.
