Enzyme immobilization is necessary process to improve the bioactivity and stability of biocatalyst. In this study, glucose oxidase (GOx) enzyme was immobilized on plasma-treated fibrous carbon felt as a textile carrier produce heterogeneous catalyst. Genipin, naturally occurring crosslinker, that has less cytotoxicity than conventional crosslinkers, used in process. UV-Vis FTIR spectra confirme...

In the study, Reactive Black 5 (RB5) was removed from synthetic wastewater using Fenton's oxidation (FO) process. Batch experiments were conducted on the samples containing 50, 250 and 500 mg/L of RB5. The study was performed in the systematic optimum value of H2O2 and FeSO4 concentrations, pH and temperature. Optimum pH and temperature for 250 mg/L RB-5 were observed at 3.0 and 40°C respective...

This study investigates the optimal conditions for preparation of corn cob based activated carbon (CCAC) for the removal of Remazol Brilliant Blue R (RBBR) reactive dye from aqueous solution. The CCAC was prepared by using physiochemical activation method which consisted of sodium carbonate (Na2CO3) and CO2 gasification. Central composite design (CCD) was used to determine the effects of the th...

This study aimed to investigate the adsorption of three commercial reactive dyes using extracellular polymeric substances (EPS) extracted from waste sludge a beer wastewater treatment plant in Hanoi, Vietnam. EPS was by HCHO-NaOH method and characterized measuring kaolin flocculation activity, dry weight, chemical composition, functional groups. Adsorption on conducted Jartest at different pH v...

Eight Aspergillus niger strains which produced strong starch degrading amylase were isolated from the soil using a medium containing Remazol Brilliant Blue (RBB) starch as substrate. Amylase production was detected by the disappearance of the blue colour around the colony. Among the isolates, A. niger AM07 produced the largest clear zone (7.0mm) on Remazol Brilliant Blue (RBB) agar plate and al...
