Calix[4]pyrrole-based porous organic polymers (P1–P3) for removing micropollutants from water were prepared. A bowl-shaped α,α,α,α-tetraalkynyl calix[4]pyrrole and diketopyrrolopyrrole monomer crosslinked via Sonogashira coupling to produce a 3D network polymer, P1. P1 proved too hydrophobic use as an adsorbent was converted the corresponding neutral polymer P2 (containing carboxylic acid group...

Currently used textile dyes are not highly toxic or carcinogenic, but the intense and persistent color of effluent is problematic. Of remediation processes investigated, adsorption process attractive, carbonaceous adsorbents (CAs) ideal for that purpose because their very high dye-binding capacity (DBC). In this review, potential biomass-based feedstocks to produce CAs application produced remo...

Decolourisation of Anionic cum acidic azo dye Amaranth was carried out by an Advanced Oxidation Process Solar/H2O2. Dye samples concentration 100 mg/L taken in 250 ml conical flasks that were treated with 30% H2O2 and exposed to sun light the intensity range 60,000-90,000 lux. The impact various parameters decolourisation like initial concentration, pH, solar intensity, additives temperature st...

The current study focuses on the development of the modified surface of the alumina by anionic surfactant sodium dodecyl sulfate. The synthesized Surfactant Modified Alumina (SMA) effectively associated with dye molecules and amended their properties. The triphenylmethane (CBB) and thiazine dyes (MB) were selected as a simulated dye wastewater system. The removal was carried out by adsorpti...

The Binding behavior of acidic capsular polysaccharide (SPS), isolated from Klebsiella serotype K43 with oppositely charged dyes and surfactants have been studied by absorbance and emission spectroscopic studies. Each repeating unit of the SPS consists of three D-mannose, one D-galactose and one D-glucuronic acid residue. The anionic polymer exhibited chromtropic character and induced strong me...

Anionic reactive dyes used to dye nylon suffer from failures due to the poor efficiency caused by low degree of exhaustion and fixation. From the previous work , the dyeing efficiency of Procion Rubine XL on modified nylon was particularly week and hence offers the widest scope for an in depth investigation in to variables that effect the dyeing process. The variables dyeing studies for this pr...
