- Abstract
Releasing phosphorus (P) in contaminated water straightforwardly into the sea-going condition prompts asset misfortune and simulates eutrophication in existence of nitrogen. In this manner, expelling P from squander streams is basic. In this investigation, Phragmites australis as an ease biosorbent was intended to viably adsorb P, total suspended solids (TSS), and total dissolved solids (TDS) from genuine modern wastewater. P. australis was portrayed through Fourier-transform infrared spectroscopy examination, trailed by SEM investigation, studying the influenced parameters, lastly, isotherm and active adsorption explore additionally occurred. P. australis was found to have favored P, TSS, and TDS biosorption capacity. The Freundlich isotherm fits the biosorption procedure satisfactorily of phosphorus, TSS, and TDS with R² = 0.998, 0.999, and 0.999, respectively. Then again, the pseudo-first-order kinetics demonstrates fits biosorption procedure of TSS with qe = 117.436 mg g−1 however, pseudo-second-order kinetics shows well fits the biosorption of P and TDS with qe = 6.5189 and 1,250 mg g−1. Hence, P. australis is an ecological neighborly and minimal effort sorbent for P evacuation.
