Adsorption of methylene blue on papaya bark fiber: Equilibrium, isotherm and kinetic perspectives
نویسندگان
چکیده
Rapid population growth and industrial expansion lead us to be habitat of a polluted planet. One the major pollutants that badly affect ecosystem being organic dyes released from various chemical industries where cleaner production concept is straightway adopted. Papaya (Carica papaya) bark fiber (PBF) natural product used for Methylene Blue (MB) dye removal as cost–effective adsorbent aqueous solution by batch method. Several parameters effect pH, initial concentration, contact time, dosage were studied optimized maximum recovery. Reaction kinetics process Langmuir Freundlich adsorption isotherms investigated. Fourier Transform Infrared (FTIR) spectroscopy Scanning Electron Microscopy (SEM) confirm surface properties PBF adsorbent. The MB uptake capacity was found 66.67 mg/g. Based on results, papaya might employed bio–sorbent exclusion dyestuffs effluent production.

Kinetic Aspects of Methylene Blue Adsorption on Blast Furnace Sludge
In the global steel industry, more than 400 kg of solid byproduct is generated per ton of steel produced. Most of this by-product (70–80 %) is in the form of slag, which is used largely in the cement industry and for road and civil construction. The remaining solid by-products can be classified as dusts, sludge and oily/non-oily mill scale. Traditionally, the majority of generated dust, sludge ...
متن کاملAdsorption Isotherm, Kinetic, and Thermodynamic Studies for Methylene Blue from Aqueous Solution by Needles of Pinus Sylvestris L
The adsorption characteristics of methylene blue (MB) onto needles of Pinus sylvestris L., an unconventional bio-adsorbent, were investigated. Maximum removal of MB was found to occur at initial pH 5. Adsorption capacity increased from 84.46 to 99.73 mg/g with an increase in temperature from 20 to 45°C at 200 mg/L of initial MB concentration. Adsorption isotherms were modeled with the Langmuir,...
