USING LOW COAST MATERIAL (SEA GRASSES) AS ADSORBENT FOR REMOVAL ERIOCHROM BLACK T DYE FROM AQUEOUS SOLTIONS

Eriochrom T Black is one of most indicators used in different applications, especially for chemical analysis it is a dye which mainly causes many problems from environmental media as a water aqueous solution.The adsorbents of activated carbon used in this study were prepared from seagrasses.The kinetic behaviour of the process was investigated.In order to study the adsorption efficiency, many parameters, such as contact time and the adsorbent ratio, were used.Langmuir and Frundlish adsorption isotherm models were tested for the adsorption process.The linear regression coefficient R2 was used to elucidate the best-fitting isotherm models.Adsorption kinetics fitted well with the first-order kinetic model.The obtained results indicated succufilly adsorpition of the studied dye using sea grasses activated carbon.
