Hypersol-MacronetTM polymers are a new series of hypercrosslinked polymeric ion-exchange sorbents under investigation for the removal of organic pollutants from potable water. Adsorption isotherms are presented for three polymers, MN-100, MN-150 and MN-200 sorbing phenol, 2-chlorophenol, 3-chlorophenol and 4-chlorophenol. Surface area and pore size distribution data are given for the polymers. The surface functionality of the Macronets determined~ by diffuse reflectance IR and X-ray photoelectron spectroscopy is presented.

## Abstract Nutshells from seven different sources (pistachio, hazelnut, almond, black walnut, English walnut, macadamia nut, pecan) were converted to granular activated carbons (GACs) by carbon dioxide activation. A portion of the GACs were oxidized with compressed air and the physical (yield, sur
The physical and chemical properties of a hypercrosslinked Macronet polymer, MN-600, have been compared with a charcoal based activated carbon, A1100, to evaluate their performance as sorbents for trace toxic metal removal from water. The characterisation includes scanning electron micrographs (SEM)
