摘要
在pH600的HAc-NaAc缓冲溶液中,Al(Ⅲ)-铬偶氮酚KS在单扫示波极谱仪上可产生灵敏的二阶导数极谱波,Ep为-046V(υsSCE)在740×10-7~133×10-5mol/L范围内,ip∝CAl(Ⅲ)回归方程为ip=323+217CAl(Ⅲ),γ=09984试验表明,该极谱波属络合物吸附波本法已用于人发中铝的测定。
In the buffer solution of acetic acid-sodium acetate(pH600),the sensitive adsorptive wave of complex of aluminium and chromazol KS was observed at -0.46V(υs.SCE)by single-sweep oscillopolarography.The height of second derivative wave is linearly related to the concentration of Al(Ⅲ) in the range of 7.40×10-7~133×10-5mol/LThe standard regression equation is ip=323+217CAl(Ⅲ),the correlaton coeffient γ=09984The method has been applied well to the determination of aluminium in hair.
