Method for measuring content of calcium hydroxide in slaked lime

The invention discloses a method for measuring the content of calcium hydroxide in slaked lime, which comprises the following steps: measuring glycerol by using a glass measuring cup, putting glycerol into a conical flask, washing the measuring cup by using distilled water without carbon dioxide, transferring residual glycerol in the measuring cup into the conical flask along with the distilled water without carbon dioxide, repeating the operation, and measuring the content of calcium hydroxide in the conical flask. After the glycerol is completely transferred, a bottle plug is arranged on the conical bottle cover; uniformly mixing, drying and cooling a slaked lime sample, weighing the sample, putting the sample into the conical flask filled with glycerol, washing the wall of the conical flask with distilled water without carbon dioxide, immediately covering a bottle plug, and shaking the conical flask to completely dissolve the sample as much as possible; taking down the bottle plug, adding a phenolphthalein
