催化分光光度法测定痕量钛周之荣1吴伟华东地质学院应化系江西临川344000催化褪色光度法测定钛的报道较少[1],本文研究了痕量Ti(Ⅳ)催化过氧化氢氧化酸性铬蓝K褪色反应的影响因素,建立了测定痕量Ti(Ⅳ)的催化光度法,并用于测定植物及人发中钛。方法...
atalytic effect of Ti(Ⅳ) on decolorizing reaction of acid chrome blue K by oxidation with H 2O 2 in H 2SO 4 solution and its dynamic conditions are studied in this paper. Based on this study, a method for the determinaton of Ti(Ⅳ) is established with the detection limits of 0.076 μg/L Ti(Ⅳ) and linear range of 0 to 60 μg/L for Ti(Ⅳ). The method has been applied to the determination of trace titanium in human hair and vegetable samples with satisfactory results.
