In this study, for the first time, a selenium-doped mesoporous biochar was prepared and efficiently employed sodium diclofenac reactive orange 16 dye adsorption. The characterization results indicated that selenium doping had remarkable impact on Biochar-Se morphological physicochemical structures. efficacy of developed samples (RO-16) (DCF) removals fully investigated. For both molecules (DCF RO-16), Liu's equilibrium model offered best fitness with maximum adsorption capacity values 355 mg g−1 DCF 538 RO-16 Biochar-Se. Multiple mechanisms including pore filling, π-π interaction, hydrogen bonding between DCF/RO-16 were involved in process. Se-nanoparticles formed metal–oxygen bonds, which boosted molecules. current work feasible approach development Se-doped adsorbent is incredibly effective treating wastewater.

Low-cost treated lignocellulosic biomass waste supported with FeCl3/Zn(NO3)2 for water decolorization

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: Sept. 30, 2022

Abstract Dye pollution has always been a serious concern globally, threatening the lives of humans and ecosystem. In current study, treated lignocellulosic biomass waste supported with FeCl 3 /Zn(NO ) 2 was utilized as an effective composite for removing Reactive Orange 16 (RO16). SEM/EDAX, FTIR, XRD analyses exhibited that prepared material successfully synthesized. The removal efficiency 99.1% found at equilibrium time 110 min dye concentration 5 mg L −1 Adsorbent mass 30 resulted in maximum elimination, process decreased by increasing temperature from 25 to 40 °C. effect pH revealed optimum occurred acidic media, having greater than 90%. kinetic isotherm models RO16 elimination followed pseudo-second-order (R = 0.9982) Freundlich 0.9758) assumptions. Surprisingly, performance modified sawdust 15.5 times better raw removal. conclusion, sawdust-Fe/Zn is promising

As a result of rapid modernization caused by industrial growth, drinking water is constantly polluted various dyes. Hence, the health and environmental concerns associated with toxic dyes have received serious attention from communities around world. In this work, novel adsorbents (Ti-Arg-TES Ti-Tyr-C-APTMS) consisting Ti/Si-alkoxides/amino acids without cellulose in 1:1:1 mol ratio were synthesized methanol using sol-gel method. The organic-inorganic hybrid compounds as characterized combination FTIR, XRD, SEM, EDS, BET, BJH, other analysis methods. Then, their removal behaviors possible mechanisms for methylene blue (MB) Congo red (CR) systematically investigated. Batch adsorption experiments revealed that process between these MB or CR conformed to pseudo-second-order kinetics (R2 = 0.999 MB, R2 0.988 CR) both Langmuir 0.970 0.955 Freundlich 0.953 isotherm models, demonstrating chemical/physical process. maximum capacity was 57.14 mg/g Ti-Arg-TES 83.05 Ti-Tyr-C-APTMS.
