摘要
在溴化十六烷基吡啶存在下 ,锰与磺基水杨酸、水杨基荧光酮形成四元配合物 ,摩尔比为n(Mn)∶n(Ssal)∶n(SF)∶n(CPB) =1∶1∶1∶1 ,λmax=590nm ,ε5 90 =1 .58× 1 0 5 .锰在 9.2~ 1 0 2 μg/L ,符合比耳定律 ,回归方程为 :A =- 0 .0 0 1 2 7+ 0 .0 1 59× 1 0 7C ,相关系数r =0 .9982 ,平均回收率为98.4 % .
With the existence of the cetylpyridine bromide, manganese, sulfosalicylic acid and salicylfluorone can make up a coordination tetracompound. Mol ratio is n (Mn): n (Ssal): n (SF): n (CPB)=1∶1∶1∶1, λ max =590nm, ε 590 =1.58×10 5. The concentration of Mn is 9.2~102μg/l, which is coincident with the Beer's law, the regression equation is A = 0.001 27+0.015 9×10 7C, the correlation coefficient is r =0.998 2, the average recovery ratio is 98.4%.This method can be used to determine the Mn content of the running water.
