High Adsorption Capacity

Steamed Hoof Powder (SHP), size < 53μ, was observed to have high adsorption capacity for Hg(II) with >95% removal from a solution containing 100 mg/L of Hg(II) with only 0.1% (W/V) concentration of SHP. The SHP has good settling properties and gives clear and odour free effluent. Studies indicate that pH values between 2 and 10 have no effect on the adsorption of Hg(II) on SHP. Light metal ions like Na+, K+, Ca2+ and Mg2+ up to concentrations of 500 mg/L and heavy metals like Cu2+, Zn2+, Cd2+, Co2+, Pb2+, Ni2+, Mn2+, Cr3+, Cr6+, Fe2+ and Fe3+ up to concentrations of 100 mg/L do not interfere with the adsorption process. Anions like sulphate, acetate and phosphate up to concentrations of 200 mg/L do not interfere. Chloride interferes in the adsorption process when Hg(II) concentration is above 9.7 mg/L. The adsorption equilibrium was established within two hours. Studies indicate that adsorption occurs on the surface sites of the adsorbent.

Main Component

The aim of research: comparative study of adsorption capacity and selectivity of enterosorbents of different generations. Material and methods. The subject of the study is enterosorbents widely applied in clinical practice. They belong to different generations and exhibit different adsorption capacities and different doses of daily application. Results. It was found out that enterosorbents differed from one another and the latest generation had more perfect and diverse adsorption properties. The experimental data confirmed that enterosorbents of the fourth generation, in particular white carbon, whose main component is silicon dioxide exhibited a highly developed active surface and high adsorption capacity relative to highly toxic heavy metals, while its ability to bind and remove useful components (biometals and vitamin C) in organism was negligibly low. Conclusions. The enterosorbent of the fourth generation «White coal» possess high adsorption capacity toward heavy metals and simultaneously are characterized by negligibly low capacity to bind and remove bioactive compounds such as biometals and vitamin C.

Many researchers have used activated carbon as adsorbents for the adsorption heavy metal. The aim of present study was to investigate the adsorption properties of activated carbon for the removal of Fe metal. A research has been conducted to determine optimal of stirring time, stirring speed, adsorbent mass and particle size on activated carbon adsorbent in adsorption Fe metal. From the literature survey that increase in stirring time, stirring speed and adsorbent mass enhancing the removal of Fe metal. The results show which is on stirring time 60 minutes, stirring speed 90 radians per minute and adsorbent mass 2 grams have a high adsorption of the heavy metals of iron. Whereas the smaller of particle size enhancing the adsorption of Fe metal. The particle size of 200 mesh is the optimal particle size for adsorption of Fe. Finally, activated carbon showed to be a good potential adsorbent for removing Fe.
