The main intention of this work is to study the adsorption rate and mechanism for the adsorption of Malachite Green dye (MG) onto Jordanian diatomite. A series of experiments were conducted under a variety of conditions such as the mass of diatomite, initial MG concentration, and pH of the solution. The mechanism of adsorption was elucidated based on different kinetic models. Experimental conditions showed a considerable effect on the adsorption rate. Alkali conditions promote MG uptake and increase the rate of adsorption. Approximately 99% of dye removal was achieved as the diatomite dosage increased from 0.25g to 1.5g. The adsorption rate-controlling step was found to be a combination of chemisorption and intraparticle diffusion, with the external mass transfer predominating in the first five minutes of the experiment.

Adsorption of Malachite Green (MG) on activated carbon obtained from Teak wood biomass has been investigated by batch adsorption method. The percentage removal of dye has been optimized by studying the initial concentration of the dye, adsorbent dosage, adsorption time and pH. The experimental data were found to be well fitted to Langmuir isotherm. The present study indicates that activated carbon obtained from Teak wood biomass is an effective adsorbent of MG dye. The prepared activated carbon was evaluated for antimicrobial activity against (Staphylococcus aureus, Escherichia coli and Aspergillus flavus, Aspergillus niger), using disc diffusion method and compared with standard antibacterial (Nitrofurantoin) and antifungal (Amphotericin B). Bacteria showing more activity than fungal strains.

The association of dyes with health related problems is not a new phenomenon. The effectiveness of carbon adsorption for dye removal from textile effluent has made it an ideal alternative to other expensive treatment methods. The preparation of activated carbon from agricultural waste could increase economic return and reduce pollution. Cassava peel has been used as a raw material to produce activated carbon. The study investigates the removal of malachite green dye from its aqueous solution. The effects of condition such as adsorbent dosage, initial dye concentration, pH and contact time were studied. The adsorption capacity was demonstrated as a function of time for malachite green from aqueous solution by the prepared activated carbon. The results showed that as the amount of the adsorbent was increased, the percentage of dye removal increased accordingly. Higher adsorption percentages were observed at lower concentrations of malachite green dye. Silver nitrate treated cassava peel showed a better performance compared to Sulphuric acid treated and raw carbons, thus making it an interesting option for dye removal textile effluent.
