<strong>Preparation of corn cob based bioadsorbent as an effective adsorbent</strong>

Abstract

The high level of production and use of dyes due to industrialization has created a great global environmental concern. These pollutants are non-biodegradable and stable to light, heat, and moderate oxidizing agents which create the serious threats to human health and marine. Hence, removal of these pollutants from discharged wastewater is a very challenging task. The aim of this present study was to utilize the residual biomass of corn for eco-friendly bioadsorbent preparation and eliminating the methyl orange (MO) from aqueous solution. The effects of initial dye concentration, bioadsorbent dosage and contact time on the adsorption capacity of the bioadsorbent were investigated. The maximum adsorption capacities of the bioadsorbent for methyl orange was 350 mg.g -1 at initial concentration of 500 mg.L -1 . Moreover, the recyclability experiments demonstrated that the bioadsorbent could be reused for at least four cycles with stable adsorption capacity. These results provide that corn cob based bioadsorbent can be utilize as an effective adsorbent for practical wastewater treatment.

Estigmas del maíz como sustrato para remoción de mercurio en aguas contaminadas

“…En este mismo sentido, biocarbón proveniente de paja de maíz y aserrín modificado con proceso de pirólisis se ha utilizado para la remoción de atrazina de soluciones acuosas y se ha alcanzado una capacidad de adsorción de 37,2 mg/g, valor que se ha alcanzado debido a modificaciones en la porosidad y en los grupos funcionales de la superficie del adsorbente (Gao et al, 2019). Por sus propiedades, la preparación y evaluación de carbones activados obtenidos a partir de biomasa de maíz para remover contaminantes, sustancias radioactivas, metales pesados, fármacos, pesticidas, disruptores endocrinos y desechos fenólicos industriales ha generado resultados favorables (Arquilada et al, 2018;Gale et al, 2021;Rahimi et al, 2017;Zhou et al, 2015).…”
