摘　　要：提出采用蒸馏水稀释法直接测定水-乙二醇型难燃液压液中钼、钠、硼元素含量的ICP方法,并对该方法的可行性进行探讨。研究表明:所测得各元素的相对标准偏差均小于10%,方法的检出限均小于1.0 mg/kg,回收率在93%以上,证实该方法简单可行。Method of determination of Mo, Na, B in water - glycol fire-resistant hydrauhc fluid by ICP through using distilled water diluting sample directly was proposed. The feasibility and accuracy of the method was discussed. The results show that the relative standard deviation（RSD） of all elements is less than 10% ,the minimum detecting limit is lower than 1.0 mg/kg,and the recovery rate is higher than 93% ,which shows the method is simple and practicable.
