化学 氢氧化钾 The sample was combusted in the oxygen bomb containing potassium hydroxide solution and liquor hydrogen peroxide. The halogen released from rubber combustion was absorbed by solution and determined by potentiometric titration with silver nitrate standard solution(0.01 mol/L). 在加有氢氧化钾溶液和过氧化氢溶液的氧弹中燃烧样品,使样品中以有机化合物或无机化合物的形式存在的总卤素的量,可以在燃烧后通过水溶液吸收或溶解于水溶液当中转化为卤化物;吸收后的溶液用0.01 mol/L硝酸银标准滴定溶液进行电位滴定。
