Adsorption of Alizarin Red from Aqueous Solution by Modified Furfural Residue

Abstract

An adsorbent was synthesized from modified furfural residue. The properties, kinetics and thermodynamics of alizarin red from water adsorption process on modified furfural residue were studied. The adsorption isotherm indicat that the relationship between adsorbing capacity (qe) and equilibrium mass concentration (Ce) is in accordanced with the isothermal adsorption equations of Langmuir. sorption process of modified furfural residue for alizarin red was decalescence reactionphysical adsorption. alizarin red as an adsorptive material was an effectual method. alizarin red as an adsorptive material was an effectual method. The exploitation and utilization of this furfural residue must bring obvious economic and social benefit to us

Microwave-Assisted Hydrothermal Carbonization of Furfural Residue for Adsorption of Cr(VI): Adsorption and Kinetic Study

“…These agriculture materials are waste lignocellulose substances, adding a certain volume of acid (5-8% dilute H 2 SO 4 ) tends to hydrolysis reaction at a particular temperature (175-185ºC) and pressure. Later, the extracted chemical substance having furfural form and the remaining amount is furfural residue, which is rich in lignin and cellulose [13]. It has been calculated that about 23 million tons/year of furfural residue is generated in China only.…”
