摘要
在6.5％酒石酸钾钠、1.25M结晶硫酸钠、2M六次甲基四胺(pH=5.8)、0.0065％聚乙烯醇(PVA—124)、0.6％铜铁试剂底液中,钛产生一个十分灵敏的吸附催化波。钛的峰电位是—0.97V(对饱和甘汞电极),钛的浓度在0.005～1.0μg/25ml范围内与峰高成线性关系。本法适用于大气悬浮颗粒中微量钛的测定。
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.
