乙二醇二乙醚二胺四乙酸(EGTA)已成为一种很有吸引力的镁存在下滴定钙的试剂,钙和镁之间的EGTA络合物稳定性的相对大的差异(logK_(cay)=11.0,
Ethylene glycol diethyl ether diamine tetraacetic acid (EGTA) has become an attractive reagent for titration of calcium in the presence of magnesium, a relatively large difference in the stability of the EGTA complex between calcium and magnesium (log K cay ) = 11.0,
