| 摘 要： | 在甲醇存在下,用EDTA四钠盐能准确而精密地络合滴定Ca(OH)2和CaCO3混合物.当甲醇与水的体积比在0.2～0.6之间时,CaCO3 对Ca(OH)2的滴定不干扰,且能准确滴定Ca(OH)2.本法可用来监测石灰乳碳化的全过程.

| Abstract: | In the presence of methanol, the mixture of Ca(OH) 2 and CaCO 3 can be analyzed with high accuracy and precision by EDTA complexometry. CaCO 3 does not interfere the titration of Ca(OH) 2,if the volume ratio of methanol to water is larger than 0 2. Between the region of 0 2 to 0 6 of the volume ratio, Ca(OH) 2 can be titrated accurately and precisely. The analytical procedure and the statistical processing of the analytical data have been discussed in detail. This analytical method has been used to inspect the whole carbonation process of the lime milk successfully. |
