中文摘要：
运动研究在层上在 orthophosphate 阴离子的吸附上被进行两倍氢氧化物(LDH ) 。吸附证明了自己是一个自发的吸热的过程并且在能力和率大。与 Freundlich 好的吸附等温线相互关联当模特儿，并且在温度的上升将在吸附效率导致增加。另外，结果建议吸附是一个增加熵的过程并且在对伪秒顺序动力学的好同意。orthophosphate 的吸附的免费精力(ΔG ) 在 −1.75 −3.34 kJ/mol 的范围以内变化到 LDH 上，热含量(ΔH ) 由 33.59 kJ/mol 由 7.96 kJ/mol 和熵(ΔS ) 变化。吸附激活精力是 8.3 kJ/mol，证明 orthophosphate 的吸附到 LDH 上决心是物理吸附。
英文摘要：
A kinetic study was conducted on the adsorption of orthophosphate anions on layer double hydroxide （LDH）. The adsorption has proved itself to be a spontaneous endothermic process and is large in capacity and rate. The adsorption isotherm correlates well with the Freundlich model, and a rise in temperature will lead to an increase in adsorption efficiency. Additionally, the results suggested that the adsorption is an entropy-increasing process and is in good agreement with the pseudo-second order kinetics. The free energy （AG） of adsorption of orthophosphate onto LDH varies within the range of -1.75- -3.34 kJ/mol, the enthalpy （AH） varies by 7.96 kJ/mol and the entropy （AS） by 33.59 kJ/mol. The adsorption activation energy is 8.3 kJ/mol, showing that the adsorption of orthophosphate onto LDH is determined to be a physical adsorption.
