采用废弃牡蛎壳粉对水中的磷离子进行吸附,研究牡蛎壳粉添加量、温度、 pH值、磷溶液初始质量浓度以及吸附时间,对牡蛎壳粉吸附水中磷离子的影响。结果表明,随着牡蛎壳添加量的增加,对磷的吸附量增加而吸附效率却在减小,其最佳添加量为0.5 g;牡蛎壳粉对磷的单位吸附量随着温度的升高而升高;牡蛎壳在酸性条件下对磷的吸附量好于碱性条件下,当pH值为5时达到最佳;牡蛎壳对磷的吸附量随着磷溶液初始质量浓度的增加而增加;牡蛎壳粉对磷的吸附量随着吸附时间的增加而增加,4 h后达到平衡状态;牡蛎壳对磷的动力学吸附过程最遵循Morris扩散模型,相关系数达到0.9901。
採用廢棄牡蠣殼粉對水中的燐離子進行吸附,研究牡蠣殼粉添加量、溫度、 pH值、燐溶液初始質量濃度以及吸附時間,對牡蠣殼粉吸附水中燐離子的影響。結果錶明,隨著牡蠣殼添加量的增加,對燐的吸附量增加而吸附效率卻在減小,其最佳添加量為0.5 g;牡蠣殼粉對燐的單位吸附量隨著溫度的升高而升高;牡蠣殼在痠性條件下對燐的吸附量好于堿性條件下,噹pH值為5時達到最佳;牡蠣殼對燐的吸附量隨著燐溶液初始質量濃度的增加而增加;牡蠣殼粉對燐的吸附量隨著吸附時間的增加而增加,4 h後達到平衡狀態;牡蠣殼對燐的動力學吸附過程最遵循Morris擴散模型,相關繫數達到0.9901。

Oyster shell waste is used to adsorb the phosphate,and the effect of dosage,temperature,pH,initial concentration,and reaction time on phosphorus adsorption is experimentally studied. The adsorption capacity of phosphate increased and the adsorption efficiency reduced with the increasing of the dosage of oyster shell waste,and the maximum adsorption capacity is achieved at an optimum dosage value of 0.5 g. The phosphate adsorption capacity of waste oyster shell increases with increasing temperature. The adsorption capacity in the condition of acidity is better than its in alkalescency,and the maximum adsorption is achieved at an optimum pH value of 5. The adsorption capacity of oyster shell waste increases with the increasing of initial phosphate concentration,the phosphate adsorption capacity of waste oyster shell increases with increasing reaction time,and the equilibrium adsorption is achieved at reaction time of 4 hours. The adsorption kinetics can be described by the Morris diffusion model with high correlation coefficient(0.990 1).
