EFFECT OF DYE CONCENTRATION ON ADSORPTION EFFICIENCY

Dye industries waste are not properly treated it is directly let in to the river so to find out economical way to remove such coloring pollutant In this work adsorption of methylene blue using various adsorbent such as groundnut shell, and tea waste were used. Among these by keeping the adsorbent dose as constant, the variation of adsorbate concentration at constant contacting time for the process. In which for Tea waste at 100 mg/L showed 70% adsorption, as increased adsorption efficiency and drops down at the mid stage & finally reaches 65% for 500 mg/L. Ground nutshell shows an unusual increase & decrease from 29% to 15% then to 53% Dye removal efficiency.
