为了提高吸附剂的利用率，降低生产成本，回收饱和镧改性松针（LH松针）作为一种可能的解决方案进行了研究。以东北林区的松针为原料，采用碱-异丙醇法和化学沉淀法制备LH松针。探讨LH松针作为再生吸附剂在污水处理厂和实验室配水中的应用。结果表明，LH松针对污水处理厂低浓度再生水中磷的去除率为41%，达到其投加标准的92%以上。在较宽的pH范围内，LH松对磷具有有效的吸附能力; pH也会干扰LH松对磷的吸附能力，二者之间存在负相关关系。在pH值为3~11的范围内，LH松针对磷的吸附可分为3个阶段。配体交换反应、静电反应和刘易斯酸反应是PO 43 −的吸附机理。通过对LH松针再生效率的分析，证明LH松针具有良好的再生性能。经NaOH再生剂洗脱10次以上，7次循环后，磷的吸附率仍稳定在90%以上。
In order to enhance the using efficiency of the adsorbent and decrease production costs, reclaimed saturation Lanthanum modified pine needles (LH pine needles) have been studied as a possible solution. Pine needles gathered from the woods of Northeast China area were used as raw material for generating LH pine needles by alkali-isopropanol treatment and chemical precipitation. To explore the utilization of LH pine needles as a recycling adsorbent in wastewater treatment plants (WWTPs) and laboratory water distribution. Results show that removal effective of phosphorus (P) by LH pine needles in low concentration reclaimed water of WWTPs was 41% and up to more than 92% in its adding standard. In the wide pH range, LH pine has an effective adsorption capacity for phosphorus; pH can also interfere with the adsorption capacity of LH pine as there is a negative correlation between them. The adsorption of phosphorus by LH pine needles is divided into three stages with a pH ranging from 3~11. Ligand exchange reaction, electrostatic reaction and Lewis acid reaction are PO43− adsorption mechanism. The analysis of the recycling efficiency of LH pine needles proved that LH pine needles have good regeneration performance. After being eluted by NaOH regeneration agent for more than 10 times, the adsorption efficiency of phosphorus can still be stable at over 90% in seven cycles.
