PARAMETRIC OPTIMIZATION OF DYES ABSORPTION USING POLYPROPYLENE IMINE DENDRIMER FROM TEXTILE WASTEWATER
Recently, Dendrimers are famous for monodispersed, highly branched, three dimensional, macromolecular nanoscopic architecture with several groups of the reactive end. Dendrimers work as dye removal agents from the two systems liquid-solid or liquid-liquid. This study tackles the textile dyes removal from aqueous solutions by Reactive Black 5 (RB5), Acid Blue 7 (AB7), Reactive Red 198 (RR198), Acid Green 25 (AG25), poly (propylene imine) dendrimer (PPI). and have been utilized as model dyes. Operational parameters influence the removal of dye like the concentration of dye, the concentration of dendrimer, pH, time, and temperature were investigated. Findings revealed that the efficiency of dye removal was maximized by increasing both concentrations of dye and dendrimers. Furthermore, results showed that the adsorption of dyes was supported by acidic pH through dendrimer. Besides, tests showed that maximum dyes removal were achieved at time 16h and temperature around 60 °C. As the data revealed, it can be concluded that dendrimers are adsorbent which is environmentally friendly with somehow big adsorption ability of could be an advisable substitute for dyes elimination from coloured textile wastewater.
