本文采用十六烷三甲基溴化铵（CTAB）修饰碳糊电极阳极溶出伏安法测定钛。电极组成：石墨粉：液体石蜡油为2．5：1（W／V）；溶液组成：0．02mol／L酒石酸，pH4．7HAC－NaAc0．1mol／L缓冲液，CTAN浓度为5．0×10－4mol／L为最佳测试条件。电极在-0．8V富集3min，峰电流与Ti（IV）浓度在0．05～2．0mg／L范围内呈线性关系。本法用于钛矿石样品中的钛的测定，测定标准偏差0．089％，相对误差为-4．9％。
In this paper, hexadecane trimethyl ammonium bromide (CTAB) modified carbon paste electrode anodic stripping voltammetry for the determination of titanium. The composition of the electrode: 0.02 mol / L tartaric acid, pH 4.7 HAC-NaAc 0.1 mol / L buffer solution, the CTAN concentration was 5.0 × 10-4mol / L for the best test conditions. The electrode was enriched at -0.8 V for 3 min and the peak current was linear with the concentration of Ti (IV) in the range of 0.05-2.0 mg / L. This method is used for the determination of titanium in titanium ore samples, with a standard deviation of 0.089% and a relative error of -4.9%.
