- 中文摘要: The composition and stability of the complex formed between chromium (VI) and Glycine Thymol Blue (G.T.B.) has been investigated using a spectrophotometric method. the chelate is reddish brown in colour and has λmax 570nm against a regent blank. The composition has been determined by different methods as 1:1. The chelate gives maximum absorbance between pH 6.5 and 7.0. the values of log K as determined by two different methods are 5.21±0.1 and 5.24±0.1 and the values of ΔG° are -7.08±0.1 and -7.12±0.1 kcal respectively at pH 6.8 and at 25℃.
