摘要：

In the present work H2PO4- and HpO(4)(2-) ions adsorption onto organic matter (OM) obtained from ground dried three plants growing in and zones of Morocco has been studied. The adsorption process is affected by various parameters such as contact time, particle size and initial concentration of phosphate solution (C-i <= 30 mg/l). The uptake of both ions is increased by increasing the concentration of them selves. The retention of phosphate ions by Asphodelus microcarpus, Asparagus albus are well defined by several isotherms such as the Langmuir, Temkin and Freundlich.
