The thermodynamic equilibrium diagrams of Mg2＋- 3-4PO - ＋4NH -H2O system at 298 K were established based on the thermodynamic calculation. From the diagram, the thermodynamic conditions for removing phosphorus from the tungstate solution by magnesium salt precipitation were obtained. The results show that when the concentration of total magnesium increases from 0.01 mol/L to 1.0 mol/L, the optimal pH for the phosphorus removal by magnesium phosphate decreases from 9.8 to 8.8. The residual concentration of total phosphorus almost keeps the level of 4.0×10-6 mol/L in the system. MgHPO4, Mg3（PO4）2 and the mixture of Mg3（PO4）2 and Mg（OH）2 are stabilized in these system, respectively. However, increasing the total concentration of magnesium has little effect on phosphorus removal by magnesium ammonium phosphate, while it is helpful for phosphorus removal by increasing the total ammonia concentration. The calculated results demonstrate that the residual concentration of total phosphorus can decrease to 5.0×10-7 mol/L as the total concentration of ammonia reaches 5.0 mol/L and the optimal pH value is 9-10. Finally, verification experiments were conducted with home-made ammonium tungstate solution containing 50 g/L WO3 and 13 g/L P. The results show that when the dosage of MgCl2 is 1.1 times of the theoretical amount, the optimum pH for removing phosphorus is 9.5, which matches with the results of the theoretical calculation exactly.

以硅溶胶为主要原料,通过硅溶胶体系的凝胶过程中添加干燥控制化学添加剂(DCCA),并结合非超临界干燥技术制备了硅气凝胶,研究了DCCA对凝胶过程和最终所得气凝胶品质的影响。DCCA能使凝胶的生成时间增加,凝胶结构均匀化,构成凝胶的基本微粒的粒径有所减小。在一定的DCCA添加量范围内,随着DCCA添加量的增加,所得气凝胶样品的密度有所减小,比表面积增加,微观结构变得更加完善,孔分布也更加集中。不同DCCA对气凝胶品质的影响规律不尽相同,气凝胶的品质就有可能通过调节添加DCCA的种类和量得到控制。

An adsorbent, Na1.6Al0.6Ti1.4（PO4）3 （or NATP）, was prepared by controlled crystallization of glasses in the Na2O-Al2O3-CaO-TiO2-P2O5 system. The crystalline phases characterized by X-ray diffraction （XRD） show that the sample glasses crystallizes into two phases, i.e. NATP and Ca9Al（PO4）7, while the Ca9Al（PO4）7 phase can be leached selectively with HCl, leaving a massive number of pores in the material. Through the experimental research, the effects of contact time, solution pH, and the initial concentration of Na＋on the cation exchange properties were investigated. The batch sorption kinetics and equilibria can be described by Pseudo-second-order kinetic equations and Langmuir isotherm equations respectively. Furthermore, the experiments with an industrial solution show that the removal rate of sodium from industrial （NH4）2WO4 is higher than 97%. Cycle experiment also shows that the NATP has a good cyclic performance.
