Abstract

Today, textile industry produces dye wastewater which cause huge wellbeing risks to living organisms and degradation of the environment. The aim of this research was to study the capability of adsorption technique for dye removal from textile industry by using the mixture of nanocrystalline cellulose and eggshell powder (NCC+ESP) adsorbents. In this study, NCC+ESP adsorbents found to have high surface area and porosity from the characterization study which prove that they are suitable for adsorption. Adsorption studies were also carried out to determine the effect of adsorbent dose (8 g NCC+2-8 g of ESP), contact time (5-60 minutes), initial dye concentration (100-300 ADMI) and pH (2-10). Result from the determination of adsorbent dosage have shown that 8 g of NCC+5 g of ESP was the optimum amount for adsorption of dye which achieved 82.667% of dye removal. Equilibrium was attained at 30 minutes which reflects the maximum adsorption capacity. The extent of dye removal decreased from 90% to 84% with increase in the initial concentration of the dye. The adsorption capacities were shown to be favored at pH 6 which achieved 82.667% of dye removal. Lastly, this study also investigate the stability of NCC+ESP adsorbents after multiple batch adsorption cycles and the result found out that it can be considered reused effectively as the percentage of removal dye just a slightly decreased from 84% to 74%. In conclusion, this research indicated that NCC+ESP adsorbents could be efficiently and economically applied in removing dyes as well as reusing of these adsorbents could be employed as an alternative for dye remediation in the textile industrial.
