EDTA络合滴定法%螯合型%L-天门冬氨酸钙
EDTA絡閤滴定法%螯閤型%L-天門鼕氨痠鈣
EDTA락합적정법%오합형%L-천문동안산개
目的通过实验确定EDTA络合滴定法测定螯合型L-天门冬氨酸钙中钙含量的可行性。方法利用在pH=11.0的条件下,L-天门冬氨酸(螯合)钙的稳定性明显小于EDTA络合钙的特点,采用EDTA络合滴定法测定钙易达片中L-天门冬氨酸钙中钙的含量。结果平均回收率为102.46%,RSD为1.02%(n=5)。结论采用EDTA络合滴定法测定螯合型L-天门冬氨酸钙中钙含量的方法可行,结果准确可靠。
目的通過實驗確定EDTA絡閤滴定法測定螯閤型L-天門鼕氨痠鈣中鈣含量的可行性。方法利用在pH=11.0的條件下,L-天門鼕氨痠(螯閤)鈣的穩定性明顯小于EDTA絡閤鈣的特點,採用EDTA絡閤滴定法測定鈣易達片中L-天門鼕氨痠鈣中鈣的含量。結果平均迴收率為102.46%,RSD為1.02%(n=5)。結論採用EDTA絡閤滴定法測定螯閤型L-天門鼕氨痠鈣中鈣含量的方法可行,結果準確可靠。
