DETERMlNATION OF TRACE TITANIUM SUSPENDED PARTICULATES FROM THE ATMOSPHERE BY OSCILIOSCOPIC POLAROGRAPHY

Shen Tiancai Fu Meifang Liu Zhengchuan Yi Zhenkai (Institute of Labour Hygiene & Protection,Panzhihua Iron & Steel Co.) Yang Zhengwen (School of Public Health,West China University of Medical sciences)  
In the solution of 6.5% sodium potassium tartrate,1.25M sodium sulfate crystal,2M hexamthylene tetramine(pH=5.8), 0.0065% polyvinyl alcohol PVA-124,0.6% cupferron, the Titanium forms a good and sensitive adsorption catalytic wave. The peak potential of ti tanium is-0.97V(VS.SCE). The peak height is a linear relation with the concentration of titanium in the range of 0.005—1.0ug/25ml. This method is applicable to determinate trace titanium in the suspended particulates from the atmosphere.
