Mitigation of dyes from effluents of industries using dyes is a big problem as it affects not only BOD, COD but also decreases photosynthesis in aquatic plants as it obstucts penetration of sun light into the water.Till now no single technology and adsobent is known to meet desired results. In this study attempts have been made to prepare Steam Activated Pigmented rice Husk Carbon fron easily available, cheap agriculural waste. This book sheds light on optimization of parameters viz initial concentration of dye, adsorbent dose, temperature along with intra particle diffusion, thermodynamic study and kinetic study of adsorption. This book will be a significant tool for researchers and professionals who want to develope cost effective adsorbent to mitigate dyes, toxic compounds and heavy metals from the effluents also to optimize parameters.
