Abstract:The research was aimed to investigate the effect of decolourisation of Alizarin yellow dye from aqueous solutions using Al-Fe layered Hydroxide clay.Batch adsorption technique was employed to determine the optimum values of some parameters i.e initial dye concentration (10 – 50 mg/l), contact time (10 – 50 minutes) and adsorbent dose (0.1 – 0.5 g). The results obtained indicate that the dye concentration decreases with increase in contact time and adsorbent dosage.The Adsorption isotherms observed showed that … Show more
