摘　　要：系统研究了钼 (Ⅵ ) -硫氰酸钾 -结晶紫显色体系在石蜡相中的显色反应。在硫酸介质中 ,此缔合物能定量被石蜡吸附。钼量在 0～ 8μg/2 5mL范围内符合比尔定律 ,线性回归方程为ΔA =0 .0 10 2 + 0 .0 9986C(μg/2 5mL) ,相关系数r=0 .996 8。方法应用于钢铁样品中微笑量钼的测定 。Molybdenum(Ⅵ)-potassium thiocyanate-crystal violet colour reaction in paraffin phase has been studied.In the sulfuric acid medium,the coloured ion associate can be quantitatively absorbed by paraffin.Beer's law is obeyed in the range of 0 to 8 μg/mL of molybdenum.The linear regression equation is ΔA=0.010 2+0.099 86 C(μg/25 mL),the relative coefficient r=0.996 8.The method has been applied to determination of molybdenum in steel with satisfactory results.
