Study of Different Parameters on Removal of Methyl Violet Dye Using Coconut Shell Powder as an Adsorbent

Abstract

The dyeing business is one of the most water- intensive industries. The effluent from the dyeing industry comprises a variety of chemicals and coloring compounds, and it must be properly treated before being dumped into any water body. However, dye house effluents are extremely difficult to treat properly because to their considerable variability in composition. In most cases, a combination of multiple techniques of treatment is required to eliminate all toxins from the wastewater. As a result, adsorption became one of the most efficient ways for removing color from textile effluent. In this paper, an attempt is made to remove the colored ingredient Methyl Violet present in the colored solution by using a cheaply available adsorbent, coconut shell powder of specific size. In this work, the effect of variation in the parameters like dosage of adsorbent, temperature of the solution and initial concentration of the solution are studied and the adsorption removal efficiency is studied through an experimental approach. The adsorbent used is dry coconut shell of size -100 BSS mesh number. The dosage of adsorbent was varied from 10 gms to 50 gms and It was discovered that the adsorption removal efficiency was varying between 72.9 % to 89.6 %. The Additional factors that were examined are effect of temperature on adsorption and effect of initial concentration. The temperatures varying from 500C to 700C. It was determined that the adsorption removal effectiveness of Methyl Violet was found out to be decreasing from 64.6 % at 500C to 47.9 % at 700C. Adsorption efficiency was shown to decrease as temperature increased. The initial adsorbent concentration ranged from 30 to 70 ppm. It was shown that increasing the starting concentration enhanced the adsorption removal effectiveness from 85% to 88%. Based on the results of the preceding experiments, it is possible to infer that coconut shell powder is an efficient adsorbent for removing Methyl Violet from waste water, with an 89.6% removal rate.
