Second-order kinetic model for the sorption of cadmium onto tree fern: a comparison of linear and non-linear methods.

Utilization of agro-industrial and municipal waste materials as potential adsorbents for water treatment—A review

Corrosion is an unavoidable but a controllable process. Due to the issues of toxicity of substances like chromate inhibitors, there is an increasing interest in exploration and utilization of eco-friendly inhibitors, which are also known as green inhibitors. This review briefly discusses some of the interesting features of the green inhibitors reported during the last decade.

Green Inhibitors for Corrosion of Metals: A Review

Mercury adsorption on a carbon sorbent derived from fruit shell of Terminalia catappa

Carbonised jackfruit peel as an adsorbent for the removal of Cd(II) from aqueous solution

A carbonaceous sorbent prepared from an indigenous agricultural waste, jack fruit peel, by acid treatment was tested for its efficiency in removing basic dyes. Malachite green, a common basic dyestuff of triphenyl methane series used for dyeing silk and wool directly and cotton mordanted with tannin to deep green, was chosen for investigation. The process parameters studied include agitation time, initial dye concentration, carbon dose, pH and temperature. The adsorption followed first order reaction equation and the rate is mainly controlled by intraparticle diffusion. Freundlich, Langmuir and Redlich-Peterson isotherm models were applied to the equilibrium data. The adsorption capacity (Q0 ) obtained from the Langmuir isotherm plot was 166.37 mg g- 1 at an initial pH of 6.0 and at 32 ± 0.5°C. The influence of pH on dye removal was not significant and the adsorption capacity increased with increase in temperature. A portion of the dye was recovered from the spent carbon using 50% acetic acid (vlv). The discharge of highly coloured effluents into natural water bodies is not only aesthetically displeasing, but it also impedes light penetration, thus upsetting biological processes within a stream. In addition, many dyes are toxic to some organisms causing direct destruction of aquatic communities 1 • Some dyes can cause allergic dermatitis, skin irritation, cancer and mutation in man 2 • Recent estimates indicate that, approximately, 12 % of synthetic textile dyes used each year are lost during manufacture and processing operation and 20 % of these dyes enter the environment through effluents that result from the treatment of residual industrial waters 3 . Among the various classes of dyes, basic dyes were found to be the brightest class of soluble dyes used by the textile industry as their tinctorial value is very high 4 .

Basic dye adsorption on a low cost carbonaceous sorbent- Kinetic and equilibrium studies

The adsorption capacity of Methylene blue from aqueous solution onto activated carbon prepared from Delonix regia pods (Flame tree pods) was investigated under various experimental conditions Batch mode experiments were conducted to assess the potential of the above activated carbon for the removal of Methylene blue from aqueous solution Equilibrium isotherm studies have been done by varying the following three parameters: initial concentration of Methylene blue dye solution, volume of the dye solution, and adsorbent dose on the uptake of dye from the solution Non-linear analysis was used to compare the best-fitting isotherms The equilibrium data obtained were fitted to Langmuir, Freundlich, and RedlichPeterson isotherm models
