D-R adsorption energies of 0.649 to 2.433 KJ/mol revealed physical adsorption. Maximum adsorption capacity of 9.201–523.900 mg/g was obtained by Freundlich and Jovanovic isotherms. Adsorption was very favourable as evident by the high Kiselev equilibrium constant (11.652–172.78 L/mg) and very low [R _大号的0.001-0.026值。Adsorption occurred by repulsive mechanism as indicated by Fowler–Guggenheim and Hill–de Boer negative interaction energies (−16.182 to −90.163 and −111.102 to −3328.86 KJmol^-1 _，分别），证实最大的Co（II）的吸附在pH为3的结果可以在使用楝树叶的有效吸附系统，该系统是在除去低和高含量的重金属等从废水中的钴离子的非常高效的设计中使用。SN - 1687-806X UR - https://doi.org/10.1155/2019/6452672 DO - 10.1155 /六百四十五万二千六百七十二分之二千○一十九JF - 国际期刊化学工程PB - Hindawi出版KW - ER -
