| description | The invention discloses a preparation method of modified zeolite and modified zeolite prepared by the method. The preparation method comprises the following steps: (1) drying an inorganic salt reagent to constant weight, and preparing a modified activation solution; (2) proportionally adding zeolite into the modified activation solution, transferring into a closed vessel and oscillating at the constant temperature of 50-80 DEG C for 0.5-3 hours; and (3) after the reaction in the step (2) finishes, taking out the zeolite, washing with deionized water, and drying to constant weight, thereby obtaining the modified zeolite. The modified zeolite is used for low-concentration ammonia nitrogen wastewater treatment, has the advantages of excellent adsorbability, simple preparation technique and low cost, and is recyclable.
本发明公开了种改性沸石的制备方法及制备得到的改性沸石，制备方法包括如下步骤：(1)将无机盐试剂烘干至恒重后配制成改性活化液；(2)将沸石按配比投加至所述改性活化液中，移入密闭容器中，50～80℃恒温震荡0.5～3小时；(3)步骤(2)的反应结束后，取出沸石，去离子水洗净后烘干至恒重即得改性沸石。本发明的改性沸石用于低浓度氨氮废水处理，吸附性能优异、制备工艺简便、成本低廉并可再生资源化利用。 |
