ABSTRACT This paper outlines the development of a novel, low-cost, hybrid material from chitosan-methyl esterified sericite-tannin. The adsorbent material is then successfully utilized for the efficient removal of lake nutrients and harmful algae. In a FT-IR analysis, peaks related to -OH stretching, carbonyl and carboxylic groups, and CH stretching were newly created or expanded, and microcapsules were found to facilitate the removal of harmful algae and nutrients. The hybrid microcapsules obtained high removal efficiencies of 98% TN, 98% TP, and 99% Chl-a from the lake water by a quantity of hybrid microcapsules of 1 g/L, pH (7–8), and 30 min contact time at (25–30)°C. In addition, the experimental data were applied to various harmful algae growth models and were most suitable for the Heldane model. Based on the above results, microcapsules can be applied in the field, and can be expected to rapidly remove nutrients and harmful algae. GRAPHICAL ABSTRACT

使用混合微胶囊壳聚糖-甲基酯化绢云母-单宁去除有害的湖藻和养分

摘要 本文概述了从壳聚糖-甲基酯化绢云母-单宁中开发一种新型、低成本的杂化材料。然后，吸附剂材料成功地用于有效去除湖泊养分和有害藻类。在 FT-IR 分析中，新创建或扩展了与 -OH 拉伸、羰基和羧基以及 CH 拉伸相关的峰，并且发现微胶囊有助于去除有害藻类和营养物质。通过混合微胶囊的数量为 1 g/L、pH (7–8) 和 30 分钟的接触时间，混合微胶囊从湖水中获得了 98% TN、98% TP 和 99% Chl-a 的高去除效率在 (25–30)°C。此外，实验数据应用于各种有害藻类生长模型，最适合Heldane模型。根据以上结果，微胶囊可应用于田间，有望快速去除养分和有害藻类。图形概要
