High Adsorption Capacity

In this paper,granular activated carbon GAC was used to investigate the adsorption capacity and adsorption rate of a typical nitrogen-containing organic compounds L-phenylalanine. GAC shows a high adsorption capacity for the L-phenylalanine and the adsorption isotherms conform to with Langmuir model.The pseudo-first-order equation shows the best fitting for adsorption kinetics in L-phenylalanine adsorption by GAC. Besides the factors such as the temperature, adsorption time and activated carbon quantity were studied.

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.

High Adsorption Capacity

Investigate the possibility of treating wastewater containing heavy metals Zn2+ with activated carbon material prepared from macadamia shell with chemical activating agent H3PO4, showing high efficiency of adsorption of Zn2+. The results of the study showed that activated carbon with H3PO4 activating agent has high adsorption capacity, capable of handling Zn2+ best at pH = 4.5, dosage 1.8 g/L and time is 120 minutes. . The results show similarities with other research results and are capable of treating wastewater containing heavy metals Zn2+.
