by

Imane Bechohra et al. View all

Issue 4

Water and wastewater treatment and reuse

A novel technique involving hydrothermal synthesis was employed to prepare nanocomposite precursors of lamellar double hydroxide based basic mixed oxides. This method extended ongoing research on iron-impregnated hydrotalcite-supported nanomaterials. The iron-based Fe/MgAl-h nanocomposite was...

Super Absorbent Polymers in Environmental Remediation

by

Dhodapkar R., Borde P. and Nandy T.

Issue 2

General

Laboratory studies reported earlier, have shown very promising results in the selective removal of dyes from aqueous solutions by a commercially available (super absorbent polymer) SAP, Jalshakti® (JS). JS is mesoporous in nature and is a potential adsorbent for the basic dyes studied. This paper...

Removal of a basic dye from aqueous solution by adsorption using rice hulls

by

El-Maghraby A. and El Deeb H.A.

Issue 1

General

The removal of dyes from colored effluents, particularly from textile industries, is one of the major environmental concerns these days. Current methods for removing dyes from wastewaters are costly and cannot effectively be used to treat wide range of such wastewaters. This work describes the use...

Removal of dyes from aqueous solutions by adsortion on mixtures of fly ash in batch and column techniques

by

Albanis T.A., Hela D.G., Sakellarides T.M. and Danis T.G.

Issue 3

General

Adsorption and removal of commercial dyes were studied in aqueous suspensions of fly ash mixtures with a sandy clay loam soil of low organic matter content. The commercial dyes, acid orange 7, acid yellow 23, disperse blue 79, basic yellow 28 and direct yellow 28 represent the widely used nitroazo...
