Peanut hull, an agricultural waste, proved to act as an efficient adsorbent for five anionic and cationic dyes. The process was found to be a pH dependent, suggesting the adsorption is controlled by interaction between the charged dye molecule and the surface charge on the adsorbent. The effect of variable parameters (contact time, pH, mass of adsorbent, dye concentration, agitation and activat...

The characterization of a spore laccase from Bacillus vallismortis fmb-103, isolated from textile industry disposal sites, is described. The activity was 6.5 U/g of dry spore with ABTS as the substrate. The enzyme was quite stable at high temperature. It retained more than 90% of its initial activity after 10h at 70 °C. The enzyme demonstrated broad pH stability in both acidic and alkaline cond...

Abstract Co and N co-modified mesoporous carbon composites (Co/N-mC) have been simply prepared at low cost from the carbonization of ZIF-67 wherein not only providing surface N-modification for promoting adsorption behavior acidic dyes, but also constructing a magnetic property convenient separation. Co/N-mC composite presented ability MO (178 mg g −1 ) > RhB (141 (T = 25 °C, pH 7.0, C 0 20 ...

Blast Furnace Slag (BFS) is a by-product of the iron ore processing industry with potential to be used in different industrial applications. In this research, BFS was examine its ability for dye removal from wastewater. The efficiency two types samples cationic methylene blue (MB) and acidic methyl orange (MO) dyes investigated results found that optimal conditions treatment wastewater were 80 ...

Synthetic food colors are important ingredients in the industry. These synthetic colorants azo dyes, majorly acidic nature such as Allura red and Tartrazine. They present sweets, carbonated drinks, meat products, candies to attract consumers. This review article is an attempt explain adverse effects of dyes their association with oral cavities cardiovascular disorders. (azo dyes) have staining ...

Herein we demonstrate a novel way of modifying the colloidal stability proteins by presence hydrophobic molecules. A protein capable self-assembly into nanofibrils (PNFs) is milled with molecular material. Upon dissolution in acidic water followed heating, are converted PNFs containing dyes. When aqueous dispersions such heated, films formed at air–water interface. The contain ordered, opticall...

Dyes are known to be harmful organic compounds for the environment since only a small amount of dyes can hazardous. So, treatment industrial dye effluent using commercial and effective catalyst is study's main objective. The adsorptive photocatalytic activity Egyptian bentonite was improved by acid treatment, followed incorporation cerium dioxide on surface via simple precipitation method then ...

In the face of global warming and shrinking resources of fossil fuels the interest in solar energy has increased in recent years. However, the low energy and cost efficiency of current solar cells has up to this date hindered solar energy from playing a major role on the energy market. Photon upconversion is the process in which light of low energy is converted to high energy photons. Lately, t...
