Rice husk has also been explored for dyes and phenols removal from water. McKay et al. [99] examined the potential of rice husk for the removal of two basic dyes, safranine and methylene blue, and adsorption capacity of 838 and 312 mg/g, respectively was reported. Sumanjit and Prasad [100] studied the removal of acidic dyes, viz. acid violet 54, acid violet 17, acid blue 15, acid violet 49 and acid red 119 from aqueous solutions using rice husk ash. The adsorption capacity was found to vary from 99.4 to 155 mg/g, suggesting rice husk ash as a good adsorbent for dyes removal.
