Investigation Of The Removal Of Arsenite Ion From Ground Water Using Fecl3??6h2o Modified Sugarcane Bagasse Biochar

Abstract

The Presence Of An Excess Arsenite Ion (As Iii) In The Human Body Leads To Serious Humans And Other Organism??S Health Problems. The Increased As (Iii) Level May Be A Result Of Natural And Anthropologic Activities. Therefore, It Is Essential To Develop Widely Available, Sustainable, Effec Tive, And Low-Cost Adsorbent For As (Iii) Removal To Combat The Problem. This Work Aimed To Syn The Size And Characterize Fecl3.6h2o Loaded Scb Bagasse Based Biochar For As (Iii) Removal From Water. Scb Bagasse Biochar Was Prepared At 450 Oc Pyrolysis Temperatures With 1hour Residence Time. The Fecl3.6h2o Loaded Scb Biochar Was Produced By Mixing Scb Biochar With 0.5m OfFecl3.6h2o Solution For 24 Hours At Room Temperature. Ft-Ir, Xrd, Bet, And Tga Were Used To Characterize The Specific Functional Groups, Crystalline Structure, Specific Surface Area, And Ther Mal Stability, Respectively. A Successful Surface Loading Of Hydroxyl Functional Groups, And Struc Ture Of The Fecl3.6h2o Loaded Scb Biochar Were Both Confirmed. The Sugarcane Bagasse (Scb)Biochar And The Fecl3.6h2o Loaded Scb Biochar Have Been Shown To Have Bet Specific Surface Areas Of 14.88 And 97.38 M2/G, Respectively. Furthermore, Investigations On The Effects Of Adsorp Tion Parameters Namely Contact Time, Adsorbent Dose, Ph, And Initial Arsenite Concentration Have Been Conducted. The Result Confirmed That 89.89% Of Arsenite Ion Was Removed From Synthetic Water At Optimum Condition Of 180 Min, 1.5 G Adsorbent Dose, The Ph Level Of 4, And 10 Mg/L Of Initial Arsenite Concentration. Furthermore, The Adsorption Parameters Such As Equilibrium Iso Therm, Kinetics, And Thermodynamic Properties Were Conducted. The Langmuir Model Provided The Best Fit For The Adsorption Isotherm Data, With A Maximum Adsorption Capacity Of 27.70 Mg/G., The Kinetic Model's Result Demonstrated That Pseudo-Second-Order, Best Fit To The Kinetic Experimental Data With A Maximum R2Of 0.9737. The Result Of The Thermodynamic Parameters Demonstrated That The Adsorption Process Is Spontaneous And Endothermic. Phosphate And Carbonate Observed Highly Compete For Active Sites On The Adsorbent During Arsenite Removal. The Removal Efficiency Of 69.16% Of As (Iii) Was Obtained After 4 Cycles Of Desorption-Adsorption Experiment, Which In Dicated Excellent Reusability Of The Adsorbent. All These Outcomes Were Shown That Fecl3.6h2oLoaded Scb Biochar Was A Wonderful, Attractive Adsorbent For The Removal Of As (Iii) From Water.
