dc.description.abstract本文以人工海水和天然海水为介质,研究了Cr(Ⅲ)被H2O2,的氧化作用,结果表明,Cr(Ⅲ)的氧化速率为介质PH和温度的函数;海水中溶解有机质的存在也将影响Cr(Ⅲ)的氧化速率,随着海水中腐殖质(HA)浓度的增加其氧化速率呈现下降趋势。其原因可解释为腐殖质对Cr(Ⅲ)的配合作用和对Cr(Ⅵ)的还原—催化作用。
dc.description.abstractThe rates of oxidation of Cr(Ⅲ)to Cr(Ⅵ) with H2O2 have been measured in artiFical seawater and natural seawater as a Function of pH and temperature at 25℃ and pH 8.05.AFirst relationship between the rate of oxidation of Cr(Ⅲ) and Cr(Ⅲ) concentration was observed.The organic matter was Found to aFFect Cr(Ⅲ) oxidation in seawater.An increase in the concentration of organic matter(HA) causes the rates of oxidation to decrease.These are attributed to the complexation and the reduction of Chromium with organic matter.
