摘　　要：本方法用消化法将有机锡变成无机锡，在沸腾的情况下被金属铝还原，还原的整个时间均在惰性气氛中进行，被还原的锡在淀粉存在时用碘标准溶液滴定，本方法的准确度为±００５％～００８％。Methods for the measurement of organo-tin were described.The organo-tin was first digestted with sulfuric acid and hydrogen peroxid to inorgano-tin.And then stannic(IV)ion was reduced to stannous(Ⅱ)ion by aluminium metal foil in an insert surroundings and in boiling state.Last stannous(Ⅱ)was titrated with standard iodine solution.The result of analysis was accurate.
