In this work, new crosslinked pyridinium poly ionic liquid and its magnetite hybrid structured composite were prepared and applied to remove the toxic dye Coomassie Brilliant Blue (CBB-R250) from aqueous solutions. In this respect, vinyl pyridine, maleic anhydride, and dibromo nonane were used to prepare crosslinked quaternized vinyl pyridinium/maleic anhydride ionic liquid (CQVP-MA). Furthermore, a linear copolymer was prepared by the reaction of vinyl pyridine with bromo nonane followed by its copolymerization with maleic anhydride in order to use it as a capping agent for magnetite nanoparticles. The monodisperse MNPs were incorporated into the crosslinked PIL (CQVP-MA) by ultrasonication to prepare CQVP-MA/Fe3O4 composite to facilitate its recovery using an external magnetic field and enhance its adsorption capacity. The chemical structures, thermal stabilities, zeta potential, particle size, EDS, and SEM of the prepared CQVP-MA and CQVP-MA/Fe3O4 were investigated. Adsorption kinetics, isotherms, and mechanisms of CB-R250 elimination from aqueous solutions using CQVP-MA and CQVP-MA/Fe3O4 were also studied, and the results revealed that the pseudo second-order kinetic model and the Langmuir isotherm model were the most suitable to describe the CBB adsorption from an aqueous solution. The adsorption capacities of CQVP-MA and CQVP-MA/Fe3O4 were found to be 1040 and 1198, respectively, which are more than those for previously reported material in the literature with reasonable stability for five cycles.

Abstract This simple method of centrifugal analysis for total protein in human breast milk is based on the change in the wavelength of the absorbance maximum of Coomassie Brilliant Blue G-250 when the dye is bound to protein. Within-run and between-day CVs were 3.8% and 4.8%, respectively. Compared with a micro-Kjeldahl method for determination of total nitrogen, the coefficient of correlation was 0.99.

Photocatalytic Processes

The presence of organic pollutants, which cannot be eliminated by conventional processes of primary and secondary treatment, can be problematic. Photocatalytic processes offer an efficient breakdown of organic pollutants into non-toxic compounds such as CO2 and H2O. This paper proposes the use of the titanium dioxide embedded in palygorskite as a photoactive material in the degradation of cationic dye, Coomassie Brilliant Blue. The system was irradiated using UV light for a maximum time of 120 minutes. The concentration of the dye used was 1.0x10-4 mol L-1 in 0.5 g L-1 of the photoactive material. The kinetics of the system was monitored by UV-Vis spectrophotometry. In 120 minutes of radiation, the process of photocatalysis reduced the initial concentration of the Coomassie Brilliant Blue dye in half.

In this study, based on colony morphology characteristics, a total of 19 fungal endophytes were isolated from root of Calotropis Procera a traditional Indian medicinal plant. All fungal isolates were screened for their dye degradation ability. The dyes used as test dyes were Rose Bengal (RB), azo dye Methyl Red (MR), Coomassie Brilliant Blue (CBB) and Methylene Blue (MB) and the concentration of each dye in the experiment was kept 100mg/L. Among the 19 fungal endophytic isolates (CPR1-CPR19), only one isolate CPR4 showed strong dye decolourization capability against all the four test dye. Dye decolourization ability by the isolate CPR4 was determined to be 97.4%, 87%, 65% and 45% for Rose Bengal (RB), Methyl Red (MR), Coomassie Brilliant Blue (CBB) and Methylene Blue (MB) respectively. Complete colour decolourization was observed with rose Bengal followed by Methyl Red. Glucose minimal medium was used for liquid and solid culture of fungal isolates. Fungal biomass production in the presence of four test dye was studied and compare with control culture of fungal endophytes. Effect of temperature, pH, stationary and agitation conditions on dye degradation was also studied.Int J Appl Sci Biotechnol, Vol 3(3): 373-380
