Abstract
In this article, we focused on using low cost bio-adsorbents such as chitosan from shrimp & crabs shells waste and amorphous carbon thin film ACTF from micro crystalline cellulose waste to prepare a new composite (ACTF/C) for removal of methylene blue (MB) dye from aqueous solution. ACTF/C composite was prepared via a novel ultrasonic co precipitation method instead of traditional chemical vapour deposition (CVD) method. The morphological and structural descriptions are performed using XRD, FTIR, TEM, TGA, SAED and SEM analysis. The analysis results showed that ACTF/C composite was prepared successfully. The effects of several parameters such as adsorbent doses (0.05–0.2 g/100 ml), temperatures (25–45 oC), initial solution pH (3–9), dye concentrations (10,25, 50, and 100 ppm) and contact time (20-80 min) on the adsorption process were examined. The kinetics, thermodynamic analyses and adsorption isotherm models were examined to estimate the empirical results. The empirical facts are properly equipped with the Langmuir isotherm (R2 = 0.997), giving an absorption capacity of more than 85 mgg-1. From kinetic details, we found that adsorption of methylene blue day across ACTF/C composite is represented by pseudo second-order model. In general, these outcomes suggest that the new ACTF/C composite provides great potential to get rid of methylene blue dye from contaminated water
