Studies on the Micro-determination of Metals by Spetrophotometry (II) Micro-determination of pb by Dithizone Method

Spectrophotometer에 의한 금속의 최상정량법에 관한 연구 (제 2 보) Dithizone에 의한 Pb의 미량정량법

Micro-determination of Lead by Dithizone Method was studied as follows: 1) Max. absorption wave length of Dithizone-pb complex in CC $l_{4}$ soln. is 510m.mu., 2) at the range of 5.gamma.-120.gamma. pb content, Bourguer-Beer's law hold good, 3) co-existence of F $e^{++}$ Z $n^{++}$, and C $u^{++}$ interfere.rfere.
