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 the Langmuir adsorption Isotherm was best fitted having the maximum decolourisation of 76.89 mg/g and R2 value of 0.986. The Al-Fe layered Hydroxide prepared was characterized by SEM, FT-IR and XRD before and after the adsorption process. The SEM results showed the porosity was roughly filled after the adsorption. The FT_IR spectra showed the presence of OH, C=O and N-CH at 3625 cm-1, 1633 cm-1 and 2806 cm-1. The XRD results indicate that the crystalline structure was not altered after the adsorption process. In this research, a low cost and effective adsorbent was used for the removal of Alizarin Yellow dye in an aqueous solution.
Hydrogels are three-dimensional crosslinked polymers with several uses in the administration and loading of drugs as well as the capacity to hold enormous amounts of water or biological fluids. Using carboxymethyl cellulose, N,N-dimethyl acrylamide (DMA), 2-acrylamido-2-methyl-1-propane sulphonic acid (AMPS), N,N-bisacrylamide (MBA) as a crosslinker, and potassium persulate (KPS) as an initiator, the CMC-g-poly(DMA-co-AMPS) was created. FTIR spectroscopy was used to characterize the CMC-g-poly(DMA-co-AMPS). In distilled water, KOH, and HCl, the CMC-g-poly(DMA-co-AMPS)'s swelling capability was assessed. CMC-g-poly(DMA-co-AMPS has the largest swelling ratio in KOH, followed by HCl, while pure water has the lowest swelling ratio. Various salt solutions (FeCl3.6H2O, CuCl2, and NaCl) were used at predetermined times in distilled water to test the effect of ionic strength on CMC-g-poly(DMA-co-AMPS). The swelling of CMC-g-poly(DMA-co-AMPS) increased with the increase in salt solution concentration, and the ionic strength of a solution is the measure of the concentration of ions in salt solutions. In salt solutions (CuCl2, NaCl, and FeCl3.6H2O), the maximal swelling ratio of CMC-g-poly(DMA-co-AMPS) is 10.5g, 10.0g, and 9.5g, respectively.
