摘要

We describe an improved cresolphthalein complexone procedure for calcium in which diethylamine is replaced by a nontoxic amino alcohol. Advantages of the procedure are increased sensitivity, excellent baseline stability, a more optimum reaction environment (pH 10.0) that eliminates blanking problems, and freedom from interference by magnesium. Values obtained by this method are not significantly different ( P 0.05) from those obtained by atomic absorption spectrophotometry.
