Application of residual brewery yeast for adsorption removal of Reactive Orange 16 from aqueous solution

Evaluated removal of reactive orange 16 (RO16) dye from aqueous solution was studied in batch mode by using kenaf core fiber as low-cost adsorbents. In this attempt, kenaf core fiber with size 0.25–1 mm was treated by using (3-chloro-2-hydroxypropyl) trimethylammonium chloride (CHMAC) as quaternization agent. Then effective parameters include adsorbent dose, pH, and contact time and initial dye concentration on adsorption by modified kenaf core fiber was investigated. In addition, isotherms and kinetics adsorption studies were estimated for determination of the equilibrium adsorption capacity and reactions dynamics, respectively. Results showed that the best dose of MKCF was 0.1 g/100 mL, the maximum removal of RO16 was 97.25 at 30°C, pH = 6.5, and agitation speed was 150 rpm. The results also showed that the equilibrium data were represented by Freundlich isotherm with correlation coefficientsR2=0.9924, and the kinetic study followed the pseudo-second-order kinetic model with correlation coefficientsR2=0.9997forCo=100 mg/L. Furthermore, the maximum adsorption capacity was 416.86 mg/g. Adsorption through kenaf was found to be very effective for the removal of the RO16 dye.

Holocellulose was separated from Coir fibre by Sodium chlorite bleaching procedure. The adsorbent was synthesized by graft-copolymerization of acrylamide onto separated cellulose using potassium persulfate as a free radical initiator. Grafting percentage and grafting efficiency were measured and found to be 74.5 and 58% respectively. Prepared adsorbent was characterized by applying Fourier Transform- Infrared Spectrophotometer, Thermogravimetric/Differential Thermal Analyzer and Scanning Electron Microscope. Adsorbent prepared from holocellulose was successfully used at different adsorbent dosage, contact time, initial dye concentration and temperature to remove "Reactive Orange-16", a reactive dye from aqueous solution. Ultraviolet-Visible Spectrophotometric measurement of the dye in untreated and treated solutions showed that 0.2 g Holocellulose and Polyacrylamide-grafted holocellulose can remove 42% and 72% of Reactive Orange-16 dye from its 10 ppm aqueous solution within 1 hrs respectively. It may be proposed that Polyacrylamide-grafted holocellulose can be used in a traditional Textile Effluent Treatment Plant (ETP) as a cost effective adsorbent/alternative for decreasing the concentration of the reactive dye in the effluent.

The concentration of surfactant is usually determined by a colorimetric method. A simplified colorimetric method for determining cationic surfactant was proposed which has advantages over the existing colorimetric method where less chemical is used and the overall time to perform the analysis per sample is reduced by half. These methods were tested based on analyzing the ionic interaction of cationic surfactant-reactive orange 16 (PBE-RO16) mixtures. A linear correlation was observed between the absorbance ratio of PBE-RO16 mixture/dye and PBE concentration. Results obtained from this study shows that the error between the two methods is only about ±20% except for PBE concentration less than 20 mg/L. Therefore, the proposed simplified colorimetric method can be considered as an alternative method for determination of cationic surfactant in aqueous solution in the future.
