Gongye shui chuli, 2021 采用重铬酸钾法测定废水中的CODCr，其中的氯离子也会被重铬酸钾氧化，从而使测定结果产生正误差，氯离子含量越高误差越大。在现有标准分析方法（重铬酸钾法）的基础上进行改进，通过增加掩蔽剂的方式掩蔽高浓度的氯离子，采用快速密闭消解法测定高氯废水中的CODCr。采用改进方法测定CODCr标样（含氯离子质量分数8%），RSD分别为6.58%（n=10）、5.47%（n=8）和5.02%（n=8）；采用改进方法测定废水样品（含氯离子质量分数7.76%）和加标样，平均加标回收率为93.9%。经验证 ...

Gongye shui chuli, 2020 冷却塔风吹损失的液滴携带较高浓度氯离子，排放至大气后会生成氯盐细颗粒物。通过对某燃煤电厂循环水系统的补水率、排污损失率、总溶解固形物浓缩倍率进行分析计算，得到风吹损失率是经验取值的2.6倍，冷却塔氯离子排放质量浓度折合烟气排放质量浓度为39.5 mg/m3，氯离子排放因子为138.5 mg/（kW·h），折合472.7 g/t标煤，推算出2018年全国火电厂冷却塔排放的氯离子量为46万t。火电厂普遍通过湿式通风冷却塔排放水溶性离子是大气污染物监管的一个漏洞。

Zhejiang Daxue xuebao. Lixue ban, 2022 为解决传统加热法合成异喹啉-离子液体存在的问题，开发了一种超声辅助合成异喹啉-离子液体的方法。通过异喹啉季铵化过程的对比研究，证明了该方法具有环保性强、产率高、反应时间短等优点。将其扩展至阴离子交换反应，发现超声辐射法有效促进了异喹啉溴化物与简单阴离子［N（CF3SO2）2］−和［PF6］−，以及与复杂阴离子2，4-二氯苯氧乙酸的阴离子交换反应。对所得到的异喹啉-离子液体进行了结构表征以及热行为和溶解度的研究和讨论。结果表明，所得液体具有良好的热稳定性，为快速、高效建立绿色多功能化离子液体库奠定了基础。

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−
