Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Gongye shui chuli, 2016 通过实验考察了聚丙烯疏水膜对低浓度氨氮废水的单级氨氮脱除率，研究了废水中的盐、钙离子和有机物等对疏水膜脱氨能力的影响。结果表明，聚丙烯疏水膜对低浓度氨氮废水的单级氨氮脱除率为50%～60%，废水中的盐分会对疏水膜的脱氨效率产生不利影响，钙离子和有机物短期内对疏水膜的脱氨效率影响不大。

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

Shuitu Baochi Xuebao, 2017 为定量描述脱硫石膏施用下盐化碱土土壤剖面盐分与淋洗水量的关系，通过室内土柱淋洗试验开展了脱硫石膏施用下不同淋洗水量对宁夏盐化碱土水盐运移影响的研究。结果表明：施用脱硫石膏对增加水分入渗和降低0—20 cm土层土壤pH、盐分含量产生了积极影响，土壤脱盐率在84.39%~95.41%之间，但较大水量的淋洗有可能会加剧土壤碱化。连续淋洗条件下，最大脱盐深度位于60—80 cm土层。脱硫石膏施用下，0—20 cm土层Cl-、Na+溶脱率随淋洗水量的增加变化不大，低淋洗水量下，SO42-溶脱率低于Na+和Cl ...

Gongye shui chuli, 2003 使用还原型脱色剂对直接染料染色废水进行脱色处理，重点研究了脱色剂用量、反应温度、pH和时间等因素对脱色反应的影响。并且将脱色后的染色废水回用于织物染色中，在染色织物的颜色特征和牢度方面进行了比较。结果表明，脱色温度的升高有利于染料的脱色，尤其对于水溶性较差的品种，脱色剂用量的增加能够促进染料的脱色率的升高。另外三种染料在自来水和回用水中的的染色织物的染色表面深度和牢度比较接近，而且染色织物之间的色差较小，这说明脱色废水可以回用于直接染料的染色中。
