Tris(2-chloroethyl) phosphate (TCEP) has been detected all over the world as a typical refractory organic phosphate, especially in groundwater. This work applied a calcium-rich biochar derived from shrimp shell as a low-cost adsorbent for TCEP removal. Based on the kinetics and isotherm studies, the adsorption of TCEP on biochar was monolayer adsorbed on a uniform surface, with SS1000 (the biochar was prepared at the carbonization temperature of 1000 °C) achieving the maximum adsorption capacity of 264.11 mg·g⁻¹. The prepared biochar demonstrated stable TCEP removal ability throughout a wide pH range, in the presence of co-existing anions, and in diverse water bodies. A rapid removal rate of TCEP was observed during the adsorption process. When the dosage of SS1000 was 0.2 g·L⁻¹, 95% of TCEP could be removed within the first 30 min. The mechanism analysis indicated that the calcium species and basic functional groups on the SS1000 surface were highly involved in the TCEP adsorption process.

三（2-氯乙基）磷酸盐（TCEP）作为典型的难熔有机磷酸盐已在世界各地检测到，特别是在地下水中。这项工作使用从虾壳中提取的富含钙的生物炭作为低成本吸附剂去除 TCEP。基于动力学和等温线研究，TCEP在生物炭上的吸附是单层吸附在均匀的表面上，SS1000（生物炭在1000℃的碳化温度下制备）实现了264.11 mg·g -1 的最大吸附^容量. 制备的生物炭在广泛的 pH 范围内、存在共存阴离子的情况下以及在不同的水体中表现出稳定的 TCEP 去除能力。在吸附过程中观察到 TCEP 的快速去除率。当SS1000的用量为0.2 g·L ⁻¹, 95% 的 TCEP 可以在前 30 分钟内被去除。机理分析表明SS1000表面的钙物种和碱性官能团高度参与了TCEP的吸附过程。
