- W2279863106 abstract "The surface of barley straw, an agricultural waste, was modified chemically using a cationic surfactant hexadecylpyridinium chloride monohydrate (CPC) and used as an adsorbent for removal of Reactive Blue 4 (RB4) from aqueous solution. The raw and surfactant modified barley straw (SMBS) were characterized by FT-IR and its elemental composition. The stability of CPC adsorbed on straw surface were evaluated by exposing to water and organic solvent. The adsorption was performed on removing of RB4 wastewater in a batch adsorption system. The effects of contact time, initial concentration and pH of solution on RB4 uptake were investigated and discussed. It was found that the removal percentage of RB4 increased with the increase in contact time. Adsorption was favorable at high acidic condition where the maximum removal of 100% was obtained at pH 3. Dye loaded SMBS was stable where percentage of desorption was less than 7% in water. The kinetic studies revealed that the kinetic data fitted well to the pseudo-firstorder model. The isotherm study also indicated that RB4 adsorption on SMBS match well with the Langmuir model other than the Freundlich model. The maximum adsorption capacity determined from the Langmuir isotherm was 29.2 mg g-1 at 25 degree Celsius." @default.
