Textile and dyes industries are generating huge amount of dye wastewater which are toxic and hazardous
to the environment. Activated charcoal based adsorption is economical treatment of waste water
and water purification. It offers an effective method for removal of organic compounds and colour
from wastewater at low cost. The present work is focused on the removal of Reactive Red 195 dye using
activated charcoal. The percentage removal of dye is strongly dependent on the input parameters
like time of agitation, temperature of system, amount of charcoal added and initial concentration of
dye. A statistical technique response surface methodology was employed to study the influence of
various input parameters on percentage of dye removal. Three-factor-three-level Box-Behnken Design
was used for design of experiments. Freundlich and Langmuir isotherms were fitted .. View More»
