【摘要】 有效Ｐ２Ｏ５是过磷酸钙水浸取的目的组分，其浸出状况对后续加工和过程技术经济有重要意义。本文用正交试验设计法对添加剂种类和浸取条件进行筛选研究。用所筛选的添加剂和条件进行过磷酸钙的浸取，既可达到较高的浸出率，又可得到质量较好的浸取液，为制取质量合格的磷制品创造了条件。更多还原

【Abstract】 The effective P205 is the objective component in water extraction of Super-phosphate. Its extraction extent is of great importance both to follow - up processingand process technical economics. In this study, the kinds of additive and extraction conditions are sieved by orthogonal designing method. When the sieved additive and conditions are used for the water extractillg of superphosphate, the higher degree of extraction of the effective P2O5 is reached,and the water extract has better quality, which provides the condition to produce calcium phosphates with higher purity.更多还原
