In the present investigation, an attempt was made to develop a treatment system for the management of atrazine bearing wastewater. The system consists of an upflow anaerobic sludge blanket ~UASB! reactor followed by an adsorption column using waste activated carbon as the adsorbent. The UASB reactor could remove more than 80% of organic matter and 40–50% of atrazine, irrespective of the concent...
Waste materials with no further treatment such as orange barks from commercial oranges may act as adsorbent for the removal of Pb. Batch kinetic and equilibrium experiments were conducted to study the effects of contact time, initial pH, adsorbent dose and initial concentration of lead. The results show that the equilibrium was achieved less than 30 min of contact time. Three adsorption isother...
The research of the present work was to investigate the removal of Rhodamine-B dye from aqueous solution by using Corchorus Olitorius-L Leaves Nano Carbon (ACONC). Generally, dyes are used in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Corchorus Olitoriu...
The plant powder of Jaswand (Hibiscus rosa-Sinensis) were activated with sulphuric acid and used as low cost easily available and renewable biological adsorbent for the removal of acid dyes (acid blue, acid red and malachite green) from aqueous solution. Batch experiments were carried out for adsorption kinetics and isotherms. Operating variable studied were pH, temperature, adsorbent dose, ini...
The removal of Methylene Blue dye from aqueous solution using a biowaste, dried Blue Green Algae was investigated in terms of variation of initial concentration of the dye solution, adsorbent dosage and pH. The optimum pH for the removal of dye by adsorption was found to be pH 7. The data obtained in this study fitted with Langmuir and Freundlich adsorption isotherms. The experimental data conf...
Activated carbons are extremely versatile adsorbents for major industrial significance, especially for metal ions recovery from wastewaters. In this study, the activated carbon prepared from the hard shell of apricot stones, an agricultural solid, which was used for the gold recovery from gold-plating wastewater is investigated. Activated carbon was produced by chemical activation with phosphor...
