The study of adsorption isotherm and selected operating variables on adsorption of reactive and direct dyes onto MgALN03-LDH / Nor Asma Yahya

The potential of Magnesium Aluminium Nitrate layered double hydroxide (MgALN03 LDH) as adsorbent for removal dye from aqueous solution was investigated. In this study, Mg/Al was synthesized by using co precipitation method. Two reactive dyes which are Reactive Red 120 (RR 120) and Reactive Orange 16...
