摘要
根据头孢拉定废水的组成和性质,经过浓缩、还原、分离三个基本步骤,确定回收四甲基胍实验的最佳条件参数,制得纯度≥99%的四甲基胍,总回收率达到65%。
According to the constitution and property of cefradine waste, the optimized parameters are fixed to recycle the tetramethyl guanidine through concentration, deoxidization and separation. The purity of the tetramethyl guanidine is over 99% and the total recovery rate is up to 65%.
