摘要
水样加高氯酸蒸干，然后在ｐＨ＝６．１±０．１的０．１ｍｏｌ／ＬＥＤＴＡ－１ｍｏｌ／ＬＮａＡｃ、０．０５％铜铁试剂底液中进行测定。Ｔｉ（４＋）的络离子于峰电位－０．８８５Ｖ处有一灵敏的吸附催化波。钛含量在１～３００ｎｇ／ｍＬ之间有线性关系，最低检出限为０．５ｎｇ／ｍＬ。
The water sample was evaporated to dryness with perchloric acid. The residue was dissolved in solution of 0. 1mol/L EDTA--1mol/L NaAc(pH±1)and 0. 05 % cupferron. In the solution titanium was determined by square wave voltammetry over the range of-0.60 -1. 10V (vs Ag/AgCl). There was a sensitive catalysis wave at peak potential -- 0. 855V,and a linear relationship between the peak current and the concentration of titanium over the range of 1～300ng/mL.The determination limit was 0. 5ng/mL.
