本文研究了1-(α-吡啶基)-5-苯基-3-(α-呋喃基)甲(月朁)的合成方法及其在非离子表面活性剂吐温-80存在下与镉的显色反应。在pH 9.5～12.0时,络合物的λ_(max)=654nm,δ_(654)=6.0×10~4。组成为Cd∶R=1∶2。镉含量在0—13微克/10毫升范围内服从比尔
In this paper, the synthesis of 1- (α-pyridyl) -5-phenyl-3- (α-furyl) methylamine and its interaction with cadmium in the presence of nonionic surfactant Tween- Color reaction. The λ max of the complex = 654 nm and δ 654 = 6.0 × 10 -4 at pH 9.5-12.0. Composition: Cd: R = 1: 2. Cadmium levels range from 0 to 13 μg / 10 ml
