OPTIMIZATION AND MECHANISTIC INSIGHT INTO REACTIVE ORANGE-16 DYE ADSORPTION FROM AQUEOUS SOLUTION USING ACID-MODIFIED PLANT-DERIVED BIOCHAR
Journal Title: Scientific Research - Year 2024, Vol 4, Issue 5
Abstract
Abstract Reactive dyes (about 50%) enter the environment through wastewater. Various physical and chemical treatment processes currently in use for dye effluent treatment are time-consuming, cost-intensive, and less effective. Alternatively, in materials science, “green” synthesis has gained extensive attention as a reliable, sustainable, and eco-friendly protocol for synthesizing a wide range of biomaterials/nanomaterials including activated biochar and graphene. In this regard, the potential of acid-modified hemp-based biochar in dye effluent treatment was explored. This research was carried out to synthesize biochar from a biological precursor, i.e., “Cannabis sativa,” commonly known as hemp. The prepared biochar was modified with 0.1 M HCl. Experiments were conducted to check the effect of different reaction parameters on acid-modified biochar. In addition, isotherms and kinetic modeling of the adsorption process were estimated for the determination of equilibrium adsorption capacity and reaction kinetics, respectively. The adsorbent showed a strong association with acidic media, adsorption efficiency at acidic pH was higher than in alkaline media. Isothermal and kinetics modeling indicate that the adsorption of selected dyes on hemp-derived biochar-based adsorbent is monolayer adsorption (Langmuir isotherm), and its chemical nature is confirmed by the high linear fit of the Langmuir isotherm and pseudo-second-order kinetic model, respectively. Adsorption through acid-modified hemp-based biochar was found to be effective for RO16 dye decolorization. It is recommended to synthesize biochar from other carbon-rich sources with a composite of different transition metals.
