Simultaneous action of surfactant modified clinoptilolite: Adsorbent of dyes and antibacterial agent
The ability of a particular banana fibre in removing reactive dyes from textile wastewater was studied in the present work. Locally available ground seeded banana fibre of ≤ 212 μ was used as adsorbent. Initially the adsorbent was tested on standard Novacron Blue FN-R reactive dye solutions and then it was also applied to raw textile wastewater. The adsorbent was found very effective to remove ...
Background & objective: Synthetic dyes are extensively used in various industries such as textile, leather tanning, plastic, pulp and paper. Since dyes are toxic and even carcinogenic, discharging dye-containing wastewater into the environment poses serious environmental and health problems. Therefore, the purpose of this paper was to evaluate the removal of Reactive Red 120 from aqueous soluti...
In this work, magnetically separable ZnO-ZnFe2O4-PPy nanocomposite as an efficient adsorbent was synthesized by two steps. At first, zinc oxide (ZnO) and ZnFe2O4 nanoparticles were synthesized using simple and facile precipitation method. Then, ZnO-ZnFe2O4 mixed oxide was modified by polypyrrole (PPy). The adsorbent was character...
The adsorption of malachite green from aqueous solution using a local low cost adsorbent, acid activated Ntezi clay, was investigated. The low cost adsorbent was activated with different concentrations of sulphuric acid and the physicochemical properties of the adsorbent were determined and the structural properties were analyzed using XRF and XRD. The adsorption process was studied as a functi...
Background and purpose: Phenol and its derivatives are used as raw material in many chemical, pharmaceutical and petrochemical industries. It is classified as priority pollutant, due to its high toxicity. In this study, the magnetic activated carbon nano-composite was used for quick removal of phenol. Materials and methods: The activated carbon was modified by magnetic nano-particles....
