【摘要】 研究了用电感耦合等离子体发射光谱法(ICP AES)测定SD40硅烷偶联剂中的硫含量。实验结果表明,测量的精密<0 5%,用ICP AES法测定结果与按BaSO4重量法测定结果对照,结果一致。更多还原

【Abstract】 In this paper,the sulphur contents in SD40 silicohydrides coupling agent have been determined by ICPAES method.It shows that the experimental preasim is lower than 05%,and the results obtained by ICP method are consistent with that of the BaSO\-4 gravimetric method.更多还原
