Conversion of Water Hyacinth into Graphene Containing Biochar for Effective Dye Removal from Textile Wastewater

Abstract

An Aquatic Plant Known As Water Hyacinth Harms Water Bodies And Endangers Aquatic Life. It Is Essential To Use The Latest Innovations To Convert This Plant Into A Useful Product. As A Result, This Plant Was Used To Produce Graphene-Containing Biochar, Which Was Used In The Removal Of Dye From Textile Waste Water. Introducing Graphene To Biochar Increased Its Application Capacity For Dye Removal In An Efficient And Cost-Effective Manner. The Physicochemical Properties Of Graphene-Containing Biochar?�?Which Is Produced From Biological Solid Waste Like Water Hyacinth?�?Were Greatly Enhanced (E.G., Surface Area, Surface Functional Groups, Thermal Stability, Etc.). Thus, Biochar Containing Graphene Was Utilized As An Adsorbent To Remove Dyes From Textile Wastewater. In This Research, The Water Hyacinth Biochar Was Produced Through Slow Pyrolysis And Then Modified By Graphene. The Product Was Characterized By Different Characterization Techniques, Such As Xrd, Ftir, , Bet, And Tga. Batch Adsorption Experiments Were Conducted In Order To Test The Removal Efficiency Of Graphene Containing Water Hyacinth Biochar. The Effects Of Different Parameters Such As Adsorbent Dosage, Contact Time, Initial Concentration, And Ph On Removal Efficiency Were Studied. The Pzc Was Found To Be 6. The Maximum Removal Efficiency Achieved Was 90.6% At The Optimum Conditions OfPh=4, Adsorbent Dosage1g, Concentration 40 Mg/L And Optimum Time Is180 Min. The Langmuir Adsorption Isotherm Is Best Fitted For This Experiment (R2 = 0.99413), And The Pseudo-Second-Order Kinetic Model Is Best Fitted (R2 = 0.99423). The Bet Analysis Result Showed That The Surface Area Of Gcwhbc Is 373.5 M2/G. The Synthesized Graphene Containing Biochar Was Applied To Real Textile Wastewater, Providing The Maximum Adsorption Efficiency Of 63.2%. Finally, Regeneration Of The Adsorbent Was Conducted To Increase The Efficiency Of The Adsorption Cycle.
