In this study, activated carbons prepared from agrowastes by chemical activation were used to remove acetic acid an aqueous solution through a batch process. The adsorbents characterized SEM, XRD, FT-IR, and point of zero charge (pHpzc). effects adsorbent dosage, initial concentration, contact time considered. Equilibrium data was tested using Langmuir, Freundlich, Temkin, Frenkel–Halsey–Hill m...

The family Herpyllobiidae Hansen, 1892 is one of the most highly transformed families among the parasitic Copepoda, grouping a few genera of uncertain ordinal placement (see López-González and Bresciani, 2001), although the arrangement of 3 aesthetascs on the antennules of herpyllobiid copepodid stages provides evidence that the family belongs to the poecilostome copepods (Boxshall and Halsey, ...

Removal of Pb 2+ from aqueous solutions using coconut shell carbons produced by KOH activation is performed in this paper. Morphology and pore structure characteristic of coconut shell carbons are analyzed by SEM and nitrogen adsorption techniques. Effects of adsorbent concentration, agitation time and initial ion concentration on the adsorption behavior are investigated, and adsorption isother...
