Sustainable wastewater treatment is one of the foremost challenges twenty first century. With ever increasing levels industrial toxic sludge disposal to water bodies, finding environment friendly and affordable options will remain a priority, especially for developing countries. Adsorption most researched used methods removing dyes heavy metals. using living non-living biomass, termed as biosorption has gained attention in last two decades due some promising results. Agricultural waste materials e.g. fruit wastes been widely dye metal sequestration from wastewater. Various researchers have analyzed potential watermelon rind (WMR) biosorbent found encouraging Functional groups such carboxyl hydroxyl are primarily responsible sorption metals into rind. The important parameters affecting contaminants were be pH co-solute concentration. Kinetic isotherm studies performed by numerous authors revealed that pseudo second order kinetic model Langmuir best suited describing WMR based feasibility reusable further proved results desorption several researchers. This paper reviews various aspects utilization contaminated water. effects factors pH, initial solute concentration, dose, activation etc. reviewed this paper.

Biochars and activated carbons as adsorbents of inorganic and organic compounds from multicomponent systems – A review

Advances in Colloid and Interface Science, Journal Year: 2022, Volume and Issue: 305, P. 102687 - 102687

Published: May 1, 2022

Biochars are obtained by biomass pyrolysis, whereas activated carbon is a biochar that has undergone chemical or physical activation. Owing to the large surface area and easy modification both solids widely applied as adsorbents. They low-costs materials, they could be regenerated their disposal not troublesome. Adsorption of heavy metals, dyes, pharmaceuticals on biochars carbons, from simple systems adsorbate containing only one compound, described extensively in literature. The present paper provides an overview reports adsorption inorganic organic compounds onto these two types adsorbents mixed systems. have been divided into those consisting of: more ions, them (inorganic ones). research this type carried out much less frequently due complicated description interactions

Hybrid Metal Oxide/Biochar Materials for Wastewater Treatment Technology: A Review

ACS Omega, Journal Year: 2022, Volume and Issue: 7(31), P. 27062 - 27078

Published: July 27, 2022

This paper discusses the properties of metal oxide/biochar systems for use in wastewater treatment. Titanium, zinc, and iron compounds are most often combined with biochar; therefore, combinations their oxides biochar focus this review. The first part presents important information about biochar, including its advantages, disadvantages, possible modification, emphasizing incorporation inorganic into structure. In next four sections, TiO2, ZnO, Fe3O4, other discussed detail. to last section probable degradation mechanisms discussed. Literature studies revealed that dispersion a oxide carbonaceous matrix causes creation or enhancement surface catalytic or, some cases, magnetic activity. Addition metallic species biochars increases weight, facilitating separation by enabling sedimentation process thus recovery materials from water medium after purification process. Therefore, based on combination reveal wide range possibilities environmental applications aquatic media purification.

Magnetite-impregnated biochar of parthenium hysterophorus for adsorption of Cr(VI) from tannery industrial wastewater

Applied Water Science, Journal Year: 2023, Volume and Issue: 13(3)

Published: Feb. 9, 2023

Abstract The tannery industry inevitably generates toxic and catastrophic wastewater, which results in a huge threat to public health water resources. Therefore, this work aimed synthesize parthenium hysterophorus-based biochar–Fe 3 O 4 composite for removal of Cr(VI) from wastewater under full factorial experimental designs the Box–Behnken, was analyzed using response surface methodology four independent factors pH (3, 6, 9), initial concentrations (40, 70, 100 mg/L), contact times (30, 60, 90 min), adsorbent doses (20, mg/100 mL). This described by high BET area 237.4 m 2 /g, XRD prominent peaks, SEM morphology corroborate FTIR multifunctionalities O–H at 3296 cm −1 , vibration ketone C–OH 1240 C–O–C 1147 Fe–O stretching 542 . maximum Cr(IV) efficiency 91.8% recorded an concentration 40 mg/L, 3, dose mL, time min, whereas minimum 17.3% observed 20 mL dose, 9, 30 min. real determined be 85.13 mg/L its remediation found 81.8%. Langmuir’s model best fit with data R 0.99 q max 400 mg/g, showing that adsorption process homogenous monolayer. In conclusion, were encouraging, appears potential candidate Cr wastewater.
