Effects of Modifying Agents on the Dyeability of Cotton Fabric using Malachite Green Dye

Abstract

Changes in thermodynamic parameters as a result of modifying agents on dye uptake of cotton fabric using malachite green (MG) dye was investigated in this study. Five modifying agents {Acetic acid (CH3COOH), hydrated Sodium carbonate (Na2CO3.10H2O), Sodium Chloride (NaCl), Ammonium sulphate ((NH4)2SO4) and Hydrogen peroxide (H2O2)} were used on cotton fabric. The equilibrium exhaustions (%E) were determined before and after modification of the cotton fabric at different concentrations which were 88.24%, 80%, 77.14%, 65.10% and 30.88% for CH3COOH, NaCl, (NH4)2SO4, Na2CO3.10H2O and H2O2 respectively. The results also showed a correlation between the standard affinity(-Δμθ) of dye on cotton fabric and the equilibrium exhaustion. The values of entropy (ΔSθ) and enthalpy (ΔHθ) change revealed the feasibility (spontaneity) and exothermic nature of the reaction. The optimum parameters were attained in acidic solution (CH3COOH) at the highest temperature (70 °C) of dyeing as it showed the highest % efficiency of 88.24%. This work established that modification of cotton fabric with modifying agents is one of the best route to improve the affinity between dye and fabric as it reduces stress, amount of dyes wasted in dyeing, time required to achieve satisfactory results leading to a cost effective environmental friendly approach in the field of cotton dyeing.

Effectiveness of photodecomposition of rhodamine B and malachite green upon coupled tricomponent TiO2(Anatase-Rutile)/ZnO nanocomposite

Abstract

In this study, mixed phase ZnO-TiO2 nanocomposite consisting of hexagonal ZnO and anatase/rutile TiO2 has been synthesized via sol-gel process.The physical and photochemical properties of samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy (UV-vis DRS), photoluminscience spectra (PL) and and photocurrent action spectra techniques. In the case of minerlization of rhodamine B (RhB) and malachite green (MG) dyes, the coupled ZnO-TiO2 nanocomposite with the suitable band structure and the lowest photoluminescence intensity showed the best photodecolorization activity. Synergistic effects between the two oxides for photocatalytic decomposition of RhB and MG are proposed to elucidate the decolorization mechanism. The lifetime of electrons and holes was prolonged in the ZnO-anatase/rutile multiple-component system, which can enhance the light harvest and the ability of generating photo-induced electron-hole pairs of active sites, and the favorable electron-transfer properties in the coupled ZnO-TiO2 nanocomposite. Therefore, the as-prepared ZnO-TiO2 nanocomposite showed an excellent efficiency towards the removal of aqueous organic dyes and it is of certain significance for environmental photocatalysis.
