Adsorption of organic compounds

Network-PIMs can adsorb phenol from aqueous solution. Hence, they can be used for the separation of organic compounds from the aqueous phase. This process can also be utilised for the separation of phenol from waste water. One such example is HATN-network-PIM, which can adsorb up to 5 mmol g . This material can also efficiently remove a low concentration of phenol from water. Another such example is PcCo-network-PIM. These network-PIMs behave like activated carbon. In contrast, PcCo-network-PIM cannot adsorb large dyes [e.g., Napthol Green B) like activated carbons. This distinct size exclusion effect is due to its small pore size.

The C, values for Sb faces are noticeably lower than those for Bi. Just as for Bi, the closest-packed faces show the lowest values of C, [except Bi(lll) and Sb(lll)].28,152,153 This result is in good agreement with the theory428,429 based on the jellium model for the metal and the simple hard sphere model for the electrolyte solution. The adsorption of organic compounds at Sb and Bi single-crystal face electrodes28,152,726 shows that the surface activity of Bi(lll) and Sb(lll) is lower than for the other planes. Thus the anomalous position of Sb(lll) as well as Bi(lll) is probably caused by a more pronounced influence of the capacitance of the metal phase compared with other Sb and Bi faces28...

Adsorption from liquids is less well understood than adsorption from gases. In principle the equations derived for gases ought to be applicable to liquid systems, except when capillary condensation is occurring. In practice, some offer an empirical fit of the equilibrium data. One of the most popular adsorption isotherm equations used for liquids was proposed by Freundlich 21-1 in 1926. Arising from a study of the adsorption of organic compounds from aqueous solutions on to charcoal, it was shown that the data could be correlated by an equation of the form ...

In general, the adsorption of organic compounds on electrodes can be classified into two categories. In the first, the molecules adsorb but retain their chemical individuality. The adsorption bond between the molecule and the adsorbate is relatively weak, and adsorbed organic molecules may exchange readily with their peer molecules from solution ...
