Zero-valent iron supported-lemon derived biochar for ultra-fast adsorption of methylene blue

نویسندگان

چکیده

Abstract Green-based materials represent a new promising class of ecofriendly and economic adsorbents. Herein, nano zero-valent iron supported-lemon derived biochar (NZVI-LBC) was prepared for the first time examined in adsorptive removal methylene blue as model pollutant. Different characterization tools were used to ensure successful fabrication NZVI-LBC composite including FTIR, XRD, TEM, XPS, VSM, BET, zeta potential analysis. It found that fabricated NZVI–supported attained propitious adsorbent criteria since it provided supreme efficient adsorption process at short time. The reckoned maximum capacity MB onto reached 1959.94 mg/g within merely 5 min. obtained data clarified fitted pseudo 2 nd order kinetic Freundlich isotherm model. Besides, be endothermic nature. In addition, revealed an excellent behavior even after seven cycles. concrete results reflect potentiality superb candidate remove cationic pollutants from their aqueous solutions.

Carbothermal synthesis of carbon-supported nanoscale zero-valent iron particles for the remediation of hexavalent chromium.

Nanoscale, zero-valent iron is a promising reagent for in situ reduction of a variety of subsurface contaminants, but its utility in full-scale remediation projects is limited by material costs. Iron nanoparticles (20-100 nm diameter) supported on carbon (C-Fe0) were synthesized by reacting iron salts, adsorbed or impregnated from aqueous solutions onto 80 m2/g carbon black, at 600-800 degrees ...

Methylene Blue Sorption Characterisation onto Orange and Lemon Peels

Chemical properties of cationic biosorbents, the orange peel and the lemon peel, have been studied. ATR and Raman spectra indicated that the functional groups in the peels structure responsible for dye sorption are carboxyl groups (COOH and COOM, M=Na,K,Ca,Mg) and hydroxyl groups (OH). Increasing the mass of the peels in water suspensions a decrease in dissociation of both, the –COOH and –COOM ...
