摘要
用光度法和化学法分别在pH2.0,4.0和5.0测定了生成羟基甲磺酸盐(HMS)的表观二级连率常数。讨论了二级速率常数与氢离子浓度的关系。计算了下列反应的速率常数:
A kinetic study of the reaction of S(IV) with CH2O to form HMS (hy-droxymethanesulfonate) was performed.Kinetic measurements were conducted at pH 2 and 4 using a UV-240 spectrophotometer, and at pH 5 by chemical method,respectively. The rate constants for the reaction in aqueous solution were determined. The relationship between second-order rate constant and the concentration of H+ was discussed. The constants for the following reactions were calculated.
