摘要
本文研究了Ga-Zincon-OP络合体系的显色反应,结果表明,该体系显色的最佳酸度为PH4.50-5.75.在OP存在下,Ga与Zincon组成比为1∶2,在625nm下有最大吸收,表观摩尔吸光系数ε=2.24×10~4,Sandell灵敏度为0.0031μg/cm^2,0-6μgGa/ml在范围内符合比尔定律.
Gallium determination for the chro mogenic of gallium-Zincon-Op system is studied in this article It shows that the composition ratio of gallium to Zincon is 1∶2 at PH 5.0 in presence of op. The maximum absorption is at 625nm. The apparent molar absorptivity is ε= 2.24×10~4 L·mol^(-1)·cm^(-1). The Beer's law is obeyed in the range of 0-6μg gallium per ml.
