摘要
通过二次回归正交组合设计实验,研究了湿法磷酸中铁、铝、镁、氟和硫酸根对CaSO4·2H2O结晶的影响。建立了这五种杂质含量对过滤时间的数学模型。
The effects of Fe3+. Al3+. Mg2+, SiF2-6. SO2-4 on the crystal of gypsum in phosphoric acid had been studied by using orthogonal regression design. Mathematical model of the effects of thpse impurities on filter time was established.
