摘要
在盐酸介质中,痕量尿素对碘酸钾氧化亚甲基蓝的反应具有抑制作用,据此建立了一种新的、简单而快速的测定痕量尿素的催化动力学方法。线性范围0～1.60μg/10 mL。利用新建立的方法对游泳池水中尿素进行了测定,取得了比较满意的结果。
amount of urea. with potassium method used to A new, simple and sensitive kinetic spectrophotometric method was reported for the determination of trace The proposed method was based on the inhibition effect of urea on the oxidation reaction of methylene blue iodate in hydrochloric acid solution. In the range of 0 - 1.60 μg/10 mL, urea can be determined. The determine trace urea in the swimming pool water obtained satisfactory results.
