Solution Changes

Acid activated carbon obtained from cheap, non-toxic and locally available banana peel was used as a low cost and efficient adsorbent for the removal of dyes methyl orange and rhodamine-B from the aqueous solution. Changes in the resulting material before and after activation and after treatment were studied by different techniques, such as SEM-EDX, XRD, FTIR measurements. Effects of duration of treatment, amount of banana peel activated carbon, pH, and initial methyl orange and rhodamine-B concentration, on the removal of dye were studied to get optimum conditions for maximum dye removal. Removal efficiency of the activated ash remains almost constant in a wide range of pH from 2.5 to 5.6. In 75 min at room temperature removal of 98.5 % methyl orange (anionic) and 99.0 % rhodamine-B (cationic) dyes with 0.1 g and 0.125 g, respectively was obtained from the contaminated water having 10 ppm dye concentration.

Gelling Time

The synthesis of biocompatible hydrogel based on poly (ethylene glycol) (PEG) and ethylene diamine (EDA) using epoxy-amine chemistry was conducted. PEG was chosen as the base material (or monomer) to synthesise hydrogels in this study due to its high hydrophilicity, biocompatibility and low toxicity properties. The effects of mole ratios of EDA to PEGDGE on the hydrogel scaffolds properties (i.e., gelling time, swelling) were investigated. It was found out for hydrogel scaffolds prepared at 1.2 and 1.4 M [PEGDG and an EDA/PEGDGE mol ratio of 0.5 in DMSO gave the optimum hydrogel properties. Swelling studies has confirmed that hydrogel prepared at 0.5 mole ratios consist of highly cross-linked network as expected.
