fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...

background and purpose:the presence of dyes in wastewaters may cause serious problems for the environment because of their high toxicity to aquatic organisms and unfavorable aesthetical impact. in the present study, multi-walled carbon nanotubes (mwcnts) were used for removal of anionic dyes direct blue 106 (db106) and acid green 25 (ag25), from water samples. materials and methods:mwcnts were ...

Background; Recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. Therefore, the aim of this study was to determine the feasibility of using Lemna minor for Acid Blue 292 (AB292) dye removal from aqueous solution and to determine the optimal conditions. Methods; This experimen...

Background & objectives: The release of dyestuff wastewaters produced in textile industry into receiving waters affects both human health and the environment. The aim of this study was to investigate the efficiency of a photocatalytic UV/persulfate process in removal of methylene blue and acid green 3 dyes from aqueous solutions. Methods: The current study was an experimental study, in which t...

The migration patterns of naive and activated T cells are associated with the expression of distinct sets of chemokine receptors, but the molecular basis for this regulation is unknown. Here we identify Krupple-like factor 2 (KLF2) as a key transcriptional factor needed to prevent naive T cells from expressing inflammatory chemokine receptors and acquiring the migration patterns of activated T ...

Professor Pennington was an advocate for quality in all aspects of nutrition support and its delivery, ensuring that the patient remained at the centre of all decisions, and that specialist artificial nutrition support was best managed by the multidisciplinary nutrition team and the education of the wider healthcare community. Within the conference theme of ‘Quality’, this commentary aims to ou...

www.sciencemag.org SCIENCE VOL 339 18 JANUARY 2013 247 COVER Map of highest surface temperature in the north polar region of Mercury superimposed on topography measured by the MESSENGER spacecraft. Red areas surrounding the pole (center) reach temperatures above 450 K. Blue and purple areas inside polar impact craters never exceed 100 K and are suffi ciently cold to harbor water ice and frozen ...

Biosorption is becoming a promising alternative to replace or supplement the present dye removal processes from dye wastewaters. Based on the results of batch studies on biosorption of the dyes on powdered fungal biomass, Aspergillus niger, an immobilised fungal biomass was used in column studies for removal of four dyes, Acid Blue 29, Basic Blue 9, Congo Red and Disperse Red 1 from aqueous sol...
