Batch Adsorption From Solution
نویسنده
چکیده
A batch adsorption equation was derived by integrating an irreversible rate equation obtained by neglecting the desorption term of the Langmuir adsorption-rate equation. The integrated equation was in reasonably good agreement with experiment and provided a means for determining from the data the parameters gQ and ku These constants, namely, the adsorptive capacity and the adsorption rate constant, completely characterized the adsorption system at that temperature. Agreement was found between these batch adsorption parameters and their counterparts previously derived from column adsorption experiments when both types of adsorption were performed simultaneously.

Batch experimental studies of Hg(II) ion removal from aqueous solution using seven synthetic polymers
In this work application of seven synthetic polymers as adsorbents for the removal of Hg(II) from aqueous solution was studied. The equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. Variations of Hg(II) concentration in solution have been studied through measur...

متن کاملRemoval of Basic Blue 159 from Aqueous Solution Using Banana Peel as a Low-Cost Adsorbent
In this paper, the adsorption of Basic Blue159 (BB159) onto banana peel as a low-cost material was studied. At first, the banana peel was sieved. Later, banana peel particles were characterized by field emission scanning electron microscopy (FESEM), energy dispersive x-ray spectroscopy (EDXS) and Fourier Transform Infrared (FTIR) techniques. Batch adsorption experiments were carried out as a fu...
