The purity of SAM product was higher than 95％, and the overall recovery of SAM sulfate and SAM double salt of sulfate and p-tosylate were 60％ and 50％, respectively.

通过筛选，获得了对SAM有较好选择性离子交换能力、较易洗脱和再生的争光D113弱酸型阳离子树脂，研究了温度、pH等对SAM离子交换的影响，根据SAM在弱酸阳离子树脂D113上的等温交换平衡行为表现出较强的可逆性，考虑到交换基的弱电解质性质以及结合Donan膜平衡理论，建立了考虑pH影响的可逆离子交换平衡模型，该模型可以较好地描述SAM平衡浓度、pH对离子交换平衡的影响；通过对动态离子交换过程的研究，得到了SAM在D113树脂内的有效扩散系数的数量级为1.0E-9cm〓/s～1.0E-8cm〓/s。
