中文摘要：
将Zr（Ⅳ）固载在胶原纤维上制备吸附材料，研究了该吸附材料对模拟含氟、磷废水中磷酸根的吸附规律，并研究了吸附剂用量、pH值、含磷浓度对磷酸根去除率的影响。结果表明，当温度为303K，溶液中磷酸根浓度为62．0mg／L、氟离子浓度为133．0mgF／L时，胶原纤维固载Zr（Ⅳ）（ZrICF）对磷酸根的平衡吸附量为33．45mgP／g。ZrICF对磷酸根的吸附等温线符合Langmuir方程，吸附动力学符合拟二级速度方程。在优化实验条件下，ZrICF对磷酸根的去除率可达99．9％以上，同时对氟离子也有较大程度的去除。
英文摘要：
A novel adsorbent was prepared by immobilizing Zr （Ⅳ） onto collagen fiber （ZrICF）. The adsorption behavior of ZrICF to PO4^3- in PO4^3- and F-containing wastewater was studied, and the influence of adsorbent dose, pH value and phosphate concentration on phosphate removal was also investigated. The equilibrium adsorption capacity of ZrICF to phosphate was 33. 45 mgP/g at 303 K when the initial concentrations of phosphate and fluoride were 62. 0 mg/L and 133. 0 mgF/L respectively. The adsorption isotherm of phosphate on ZrICF can be described by Langmuir equation, and the adsorption kinetics of phosphate on ZrICF can be well-described by pseudo-second-order rate model In optimized condition, the removal extent of phosphate was more than 99. 9% whilst fluoride could be removed to a certain extent.
