Jingshui jishu【目的】随着全球微塑料污染加剧，以再生塑料和生物塑料为代表的新型塑料因兼具环境友好性与生态减负潜力而备受关注。新型塑料在缓解传统塑料造成的环境压力的同时，其在水中经过迁移、吸附、团聚等行为，往往以胶体态污染物形式存在，对环境造成潜在影响。与传统微塑料相比，胶体态新型微塑料(CNMPs)因胶体稳定性和新型塑料基质特性，在环境迁移、检测技术及处理工艺中表现出显著差异。【方法】本文聚焦于饮用水中的CNMPs,从其概述、检测技术、健康风险以及控制策略4个方面 ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...
