| 中文摘要:Cr(Ⅵ)作为水体中重要的污染物质,其同位素组成对水体环境变化具有较强的敏感性.铬在氧化还原过程中产生明显的同位素分馏作用,根据水体中铬的同位素组成可指示水环境中Cr(Ⅵ)的还原程度.笔者以黄石某无机盐厂周围污染水体为例,对天然水体中的铬污染及其同位素组成的相关性进行了分析研究. |

| Correlation between Chromium Contamination and Its Isotopic Composition in Natural Water |

| Abstract:As a major contaminant in water,the isotopic composition of Cr(Ⅵ)is sensitive to environmental variation.Due to obvious Cr isotopic fractionation in the oxidation-reduction process,the chromium isotopic composition in water can be used to indicate the reductive degree of Cr(VI)concentration in the water environment.Based on the study of the polluted water around an inorganic chemical factory in Huangshi City,this paper has discussed the chromium contamination and its relationship with chromium isotope ratios in natural water. |
