摘要: Abstract Heavy metals are the prominent toxic pollutant extensively present in industrial waste. Due to its toxicity nature it should be removed from In this research, raw and pyrolysis assisted dragon fruit peel along with fungal biomass (Fusarium subglutinans) was utilized as a mixed adsorbent for removal of Cr(VI) ions aqueous phase. FTIR, SEM, EDX analyses were used characterize synthesized biomasses subglutinans – RDFP Fusarium - PADFP). Batch adsorption tests reveal that optimum conditions effective onto (pH = 4.0; dosage =6.0 g/L RDFP, 3.5 g/L PADFP; temperature =30 °C; ion concentration =25 mg/L; equilibrium time =60 min). The data contact best fitted Langmiur Pseudo-first-order model, respectively. monolayer capacities found 11.0 mg/g 16.52 mg/g PADFP. Thermodynamic parameters demonstrated favorable at low temperatures exothermic process. Overall results exposed had superior capacity water/wastewater.
