This study investigated phosphorus removal from aqueous solutions using carbonatisation cake, which is a sugar residue containing a significant amount of reactive calcium carbonate. The chemical composition of the carbonatisation cake was determined, and the organic contamination of the carbonatisation cake and calcine in contact with water was determined. In addition, TGA, DTA, XRD, SEM-EDX, BET, FTIR, density, pHzpc and particle size distribution were analyzed for carbonatisation cake, product and post-phosphate removal calcined product. Batch experiments were performed to determine the effect of dose, phosphorus concentration, temperature and contact time on phosphorus removal from aqueous medium. Maximum phosphate adsorption capacity was found to be 65.16 mg g⁻¹ at 25 °C, pH of 6 and adsorbent dosage of 1 g L⁻¹ for a contact time of 180 min. Adsorption experiments were applied to adsorption isotherms. Kinetic, thermodynamic and mass transfer calculations were calculated. The results show that calcines produced by heating the carbonated cake to 600 °C, which is not cost-effective in sugar production, can be used effectively to remove phosphate from wastewaters.

这项研究调查了使用碳酸化滤饼去除水溶液中的磷的方法，该滤饼是一种含大量反应性碳酸钙的糖渣。测定碳酸化饼的化学组成，并测定碳酸化饼和煅烧与水接触的有机污染物。另外，分析了TGA，DTA，XRD，SEM-EDX，BET，FTIR，密度，pHzpc和粒度分布，以分析碳酸化饼，产物和去除磷酸盐后的煅烧产物。进行批处理实验以确定剂量，磷浓度，温度和接触时间对从水性介质中去除磷的影响。发现最大磷酸盐吸附容量为65.16 mg g ^-1在25°C下，pH为6，吸附剂剂量为1 g L ^-1，接触时间为180分钟。吸附实验应用于吸附等温线。进行了动力学，热力学和传质计算。结果表明，将糖化饼加热到600°C所产生的煅烧在糖生产中并不划算，可以有效地用于去除废水中的磷酸盐。
