Adsorption

A new magnetic Cu(II) ion imprinted composite adsorbent (Cu(II)–MICA) was synthesized with waste fungal mycelium from industry, chitosan (CS) and Fe3O4 nanoparticles combining metal imprinting technology. It was compared with its corresponding single component and magnetic non-imprinted composite ad

Nitrate content has increased in Morocco, especially in underground water of agrarian areas. Several processes including degradation processes and separation processes can remove nitrate from water. Two separating processes were studied to remove nitrate from brackish underground water: adsorption o

Activated carbon was prepared from hazelnut husks with zinc chloride activation at 973 K in nitrogen atmosphere. BET surface area of the activated carbon was found 1092 m2g!1. The removal of Cu (II) and Pb (II) ions from aqueous solutions was studied by batch method. The effects of initial pH, conta

The morphology, interspace and surface properties of a novel nanofiber membrane are characterized by scanning electron microscopy (SEM), pore percent and contact angle. The membrane, named M-1, is prepared from chloridized polyvinyl chloride by high-voltage electrospinning process. The removals of d

Slag, which consists of calcium oxide, aluminium oxide, and other metal oxides, is an abundant by-product in steel-making process. It has been used as adsorbents to remove various heavy metals and the major removal mechanisms are precipitation and adsorption on the surface of metal oxide. However, t

This work refers to the characterization of activated carbon obtained by chemical activation by KOH and ZnCl2 of a lignocellulosic material, by the techniques of adsorption of nitrogen at 77 K and immersion calorimetry in cyclohexane and water. The obtained results show that the enthalpy of immersio

In recent years, the increasing level of underground water shows a high iron and manganese concentrations, thus, the technology of water treatment requires application of processes for Fe and Mn removal. Within a literature, many treatment processes have been proposed for manganese removal from drin

In this study, the removal of nitrite from aqueous solution by adsorption was investigated. Sepiolite and powdered activated carbon (PAC) were used as adsorbents. In order to investigate the adsorption mechanisms, three simplified kinetic models, i.e., pseudo-first-order, pseudo-second-order and int

The effective removal of heavy metals from aqueous wastes is among the most important issues for many industrialized countries. Removal of lead (II) and copper (II) from aqueous solutions were studied using pomegranate peel (raw), activated carbon prepared from pomegranate peel (AC1) and activated c

Bagasse pith, which is the main waste from sugarcane industry in Egypt, has been used as a raw material for the preparation of different activated carbons. Activated carbons were prepared from bagasse pith by chemical activation with 28% H3PO4 (AC1), 50% ZnCl2 (AC2) followed by pyrolysis at 600°C an
