摘要
用无水甲醇将SSMA分离后,以钡盐及铬酸盐标准溶液作为沉淀剂和滴定剂,在六次甲基四胺——乙二胺底液中进行滴定,用交流示波极谱滴定法指示终点,由此测定SO_4^(2-)的含量。
The SSMA is seperated with absolute methanol, then the SO42- is precipitated by standard solution of Ba2+ . Exceeding Ba2+ is titrated bystaandard solution of K2CrO4 . The end poit of titration is indicated by appearance of incision on the oscillopolarographic diagram.
