摘　　要：通过络合滴定，在pH值约为13的条件下，以钙羧酸为指示剂，来测试氢氧化钙的含量。此方法滴定结果准确度较高，重现性好，对含量分析具有参考意义。The complexometric titration was studied in this article to measure the content of calcium hydroxide. When the value of pH is approximately 13, the content was determined by using calcium carboxylic acid as an indicator. The results revealed a high accuracy and good reproducibility of this method which should have important reference value to the content analysis.
