According to Figure 13, when the resin dosage was increased from 0.05 g/l to 2 g/l, the percentage of removal from 61.1% to 87.84% for lead (II), from 49.94 to 71.50% for chromium (III), and from 50.26 to 67.48 for cadmium (II) was observed. This increase in the removal percentage can be attributed to the availability of huge surface area and ...

Removal of cadmium from wastewaters with low-cost ...

For the majority of cadmium removal experiments using modified chitosan adsorbent, the optimum pH was in the range of 5–6 . 5. Competitive adsorption. Most studies focusing on Cd(II) removal by green adsorbents are performed by adding this metal ion individually in experiments dealing with adsorption-desorption process.

Removal of lead(II) and cadmium(II) from aqueous solutions ...

The sorption of lead and cadmium from aqueous solutions by grape stalk waste (a by-product of wine production) was investigated. The effects of the contact time, pH of the solution, ionic medium, initial metal concentration, other metal ions present and ligands were studied in batch experiments at 20 degrees C. Maximum sorption for both metals was found to occur at an initial pH of around 5.5.

REMOVAL OF CADMIUM (II), COBALT (II) AND NICKEL (II) …

cadmium (II), cobalt (II), and nickel (II) on corncob was observed to follow closely to the pseudo-second–order. It was concluded that corncob exhibited rapid adsorption capabilities and high efficiency in removal of cadmium (II), cobalt (II) and nickel (II) ions from aqueous solution. Keywords: adsorption, aqueous solution, agricultural ...

Cadmium(II) removal from aqueous solution using ...

Cadmium solutions were prepared daily by diluting the stock solution to the desired concentrations in high purity water (18 M Ω cm). The stock solution of cadmium(II) is extremely acidic and when it is diluted in 2 L of water, solutions with pH values around 4 are obtained. NaOH was added to these solutions in order to fix them in different pH.

Cadmium(II) removal from aqueous solution using ...

Cadmium is one of the most toxic non-essential heavy metals present in the environment, even at low concentrations. Therefore, removal of trace levels of cadmium is required. Several methods are available to remove toxic metals from aqueous waste streams, such as chemical precipitation, electrolysis (membrane separation), and ion exchange.
