Coral waste as a low cost sorbent for the removal of reactive red 198 from textile wastewater

In this batch study, natural adsorber coral to adsorb dyes evaluated from wastewater textile dye. Reactive Red Active 198 dye was intended to test. The optimum pH for removal of reactive red 198 was 13, the equilibrium contact time was 120 minutes and optimum dosage of adsorbent was 3g/100mL. In these optimum conditions, removal efficiency in synthetic and textile wastewater sample was 97.63 and 67.78 percent respectively. Based on the results according to suitable performance of coral sea as a adsorbent, its good efficiency in alkaline media and their appropriate density, rapid settling properties, not required to activation and be environmentally safe, can be proposed as an efficient adsorbent in dying wastewater treatment.
