摘要

在本文中，我们报告了液-液萃取-分光光度法对两种不同体系的研究结果，每种体系都含有W(VI)， 2-羟基-5-氯噻吩（H2L）和氨基酚（ap1,2），即2（N，N-二甲氨基甲基）-4-氯苯酚（АP1）和2（N，N-二甲氨基甲基）-4-溴苯酚（AP2）}。混合配体配合物在pH 4.1 ~ 5.2时萃取量最大。混合配体配合物（MLCs） W(V) -l - ap1,2的吸收最大值在476 ~ 480nm范围内。摩尔吸收系数为（2.3 ~ 2.4）× 104。该方法已应用于钢和土壤样品中钨的测定。

Tungsten(VI) Complexes with 2-Hydroxy-5-chlorothiophenol in the Presence of Aminophenols and Their Application

In the present paper, we report results from liquid–liquid extraction-spectrophotometric studies on two different systems, each containing W(VI), a 2-hydroxy-5-chlorothiophenol (H₂L), and aminophenols (AP_1,2), namely, 2(N,N-dimethylaminomethyl)-4-chlorphenol (АP₁) and 2(N,N-dimethylaminomethyl)-4-bromphenol (AP₂)}. Extraction of mixed-ligand complexes is maximal at pH 4.1–5.2. The absorption maxima of the mixed-ligand complexes (MLCs) W(V)–L–AP_1,2 lie in the range of 476–480 nm. The molar absorption coefficients are (2.3–2.4) × 10⁴. The proposed method were applied to the determination of tungsten in steel and soil samples.
