The impact of pH on the biochar's ability to adsorb dyes were investigated in experiments using the highest concentration and dosage possible. Different pH levels (2, 4, 6, 8, 10 and 12) were established using 0.1 M NaOH and HCl Solutions and shaken in an orbital mover and shaker at the ideal time to examine the effect of pH on dye exclusion from water. In case of Methylene blue, supreme subtraction occurs at PH 4 is 99%. In case of malachite green maximum elimination occurs at PH 4 is 81%.
