Abstract
In this research, the efficiency of activated carbon prepared from the leaves of a perennial plant called Malva parviflora plant (MPP) to remove Maxillon Blue GRL and Disperse Blue 183 dyes from aqueous solution was studied. The preparation process was carried out in three ways, firstly, using the leaves of the plant without any chemical treatment (MPP), and secondly, Activated carbon without any chemical treatment (AC-MPP), third, acid-activated carbon (AAC-MPP) with several solutions such as ((H2SO4, HCl, H3PO4, CH3COOH, and NaOH). The results that were reached indicate that the surface activated with (phosphoric acid) is characterized by its high efficiency in removal the two dye from aqueous solution, where the removal percentage reaches ( 94.69 to 84.14 % ) compared acid ( 94.44 to 79.96 % ) for Maxillon Blue GRL and Disperse Blue 183 dyes respectively. The properties of the prepared and activated surface were determined by using FESEM technique, and the functional aggregates of the surface (AAC-MPP) were also detected using the (FTIR ) technique. The role of recycling carbon prepared from the Malva parviflora plant reactivity and can be re-used again was studied.
