in the present investigation, shells of pistachio are used as adsorbents and they have been successfully used for the removal of blue 56, from water samples. the effect of various parameters such as: ph, amounts of adsorbents, size of adsorbent particles and contact time on removal processing were investigated. in this study freundlich absorption isotherms and langmuir were investigated . the e...

the use of orange peel as low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. this paper concerns with the removal of blue 56 from aqueous solutions by orange peel. the effects of ph , initial concentration, adsorbent dosage, and particle size of adsorbent, temperature and also isotherm data analys...

In this study, oxidative discoloration of Basic blue3 (B.B3) and Disperse blue56 (D.B56) dyes in synthetic textile wastewater has been studied using Fenton (Fe2+/H2 O2 ) process. The Fenton’s technique showed satisfactory color removal efficiency. The operating parameters such as concentration of Fe2+, dose of H2 O2 , initial concentration of dye, time contact, initial volume of wastewater that...

Zheng has proposed a seller-optimal auction for (asymmetric) independent-privatevalue environments where inter-bidder resale is possible. Zheng’s construction requires novel conditions—Resale Monotonicity, Transitivity, and Invariance—on the bidders’ value distribution profile. The only known examples of distribution profiles satisfying these conditions in environments with three or more bidder...

The feasibility of employing nanofiltration (NF) in the decolorization of ionic (direct blue 86) and nonionic (disperse blue 56) dye aqueous solutions was investigated. The effects of feed concentration (60- 180 mg/l), pressure (0.5- 1.1 MPa) and pH (6- 10) were studied. Experiments were performed in a laboratory- scale set up by using a TFC commercial spiral wound polyamide nanofilter. The res...

In this study, the oxidation of dye from colored wastewater by H2O2/ MWCNT’s multi walls carbon nano tubes solution assisted with UV radiation was investigated. Disperse Blue 56 DB 56 was used as a model dye. Adsorption behavior of DB56 from aqueous solution onto MWCNT’s was investigated under various conditions such as initial pH value, dye concentration, H2O2 and MWCNT’s dosage. Maximum adsor...
