In the present work, the usefulness of dried activated sludge has been investigated for the removal of copper ions from synthetic aqueous solutions. Kinetic data and equilibrium sorption isotherm were measured in batch conditions. The influence of some parameters such as: contact time, initial copper concentration, initial pH of solution and copper salt(More)
This study compares the abilities of four low-cost materials: peels of peas, broad bean, and medlar, respectively and fig leaves, to remove cadmium from aqueous solutions. Kinetic data and equilibrium sorption isotherms were measured in batch conditions. Kinetics of cadmium sorption was contact time, initial cadmium concentration and sorbent type dependent.(More)
An agricultural by-product waste: orange peel was tested for the removal of four acid dyes from aqueous solutions in batch conditions. As results obtained, kinetics of dyes sorption was time of contact, initial dyes concentration and dyes type dependent. The pseudo second-order reaction rate model adequately described the kinetics of dyes sorption with high(More)
In the present work, the usefulness of almond peel as a sorbent material has been investigated for the removal of methylene blue from synthetic aqueous solutions in batch conditions. Isotherm of dye sorption was measured. The influence of different experimental parameters such as: almond peel mass, particles size, temperature, initial pH of solution and(More)
The ability of two varieties (hard and soft) of almond peels, as inexpensive sorbents for the removal of bezanyl red (acid dye) from synthetic aqueous solutions has been studied. After their characterization by different techniques, (elemental analysis, biochemical analysis, IR spectroscopy, thermogravimetric analysis, scanning electron microscopy and(More)
In the present work, the influence of temperature on kinetics and equilibrium of methylene blue sorption from synthetic aqueous solutions, in single dye solutions, using almond peel as a sorbent material has been investigated in batch conditions. Temperature played an important part in sorption phenomenon: the methylene blue sorption increased as(More)
Batch studies of cadmium sorption by almond peel were carried out to identify the main rate controlling steps in the overall uptake mechanism, using a single external mass transfer diffusion model and intraparticle mass transfer diffusion model. The classical parameters influencing cadmium sorption mechanisms such as: initial cadmium concentration, particle(More)
The ability of thistle stalks, as an inexpensive sorbent for the removal of methylene blue (basic dye) from synthetic aqueous solutions, has been studied in batch conditions. The influence of some parameters such as: contact time, initial dye concentration, sorbent dose and agitation speed on dye sorption kinetics, has been studied. Dye uptake was time(More)
