摘　　要：本文在理论探讨和实验研究的基础上,提出了间接重铬酸钾法测定过氧化氢含量的新方法,并与高锰酸钾法、碘量法和铈量法进行了对比.实验结果表明,该法原理严谨,操作简便,选择性好,精密度高,测定结果准确可靠.A novel indirectly determination method of hydrogen peroxide by using potassium dichromate was posed,based on theoretically discussion and experimentally investigation,and the comparison with Potassium Permanganate method,iodometry and cerous sulfate was performed. The results demonstrate that the features of the method are principle s preciseness,simple manipulation,good selectivity,high exactitude and dependable result.
