日本熊本大学的 S.Stato 等最近报导一个测定锗的新方法。该法是在室温下的弱酸性水溶液中(pH 2.5—3.5),锗~Ⅳ与苯乙醇酸络合后与孔雀绿形成的离子缔合物被萃入氯苯中作光度测定的。校正曲线在(0.17-8.63)×10~(-6)M 锗浓度范围内有线性。加入
S. Stato of Japan’s Kumamoto University recently reported a new method for the determination of germanium. The method is at room temperature in a weak acidic aqueous solution (pH 2.5-3.5), germanium ~ Ⅳ with mandelic acid complexed with malachite green ion association was extracted into chlorobenzene for photometric determination. The calibration curve is linear over the (0.17-8.63) × 10 -6 M germanium concentration range. Join
