Use of titanium dioxide photocatalysis on the remediation of model textile wastewaters containing azo dyes.
The photocatalytic degradation of two commercial textile azo dyes, namely C.I Reactive Black 5 and C.I Reactive Red 239, has been studied. TiO(2) P25 Degussa was used as catalyst and photodegradation was carried out in aqueous solution under artificial irradiation with a 125 W mercury vapor lamp. The effects of the amount of TiO(2) used, UV-light irradiation time, pH of the solution under treat...
متن کاملSoure orange skin as an Adsorption for Azo dyes removal from aqueous media
In this study Soure orange skin as a good, natural and inexpensive adsorbent has been introduced and used for the removal of Erythrosine and red Carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be int...
متن کاملManganese Oxide-Surface Modified Titanium(IV) Dioxide as Environmental Catalyst
The purpose of this study is to present an “environmental catalyst” possessing both thermocatalytic activity and visible-light activity for the decomposition of organic pollutants. Molecule-sized MnOx clusters are highly dispersed on the surface of TiO2 (anatase/rutile = 4/1 w/w, P-25, Degussa) by the chemisorption-calcination cycle technique using Mn(acac)3 complex as a precursor (MnOx/TiO2). ...
متن کاملSawdust waste as a low-cost support-substrate for laccases production and adsorbent for azo dyes decolorization
BACKGROUND Laccases are multicopper oxidases with high potential for environmental and industrial applications. Low-cost laccase production could be achieved by solid state fermentation on agro-industrial by-products. METHODS A number of agro-industrial solid wastes were tested as support-substrate for laccase production by Coriolopsis gallica under solid-state fermentation (SSF) conditions. ...
متن کاملSpent Tea Leaves as a Potential Low-cost Adsorbent for the Removal of Azo Dyes from Wastewater
Spent tea leaves (STL), a solid waste that is available in large amounts worldwide, was investigated as a potential low-cost adsorbent for the removal of two azo dyes, Reactive Green 19 (RG19) and Reactive Violet 5 (RV5), from contaminated waters. Preliminary experiments conducted on untreated STL showed that this material exhibited very low removal efficiencies (<10 %). By contrast, thermal ac...
