In this study, the adsorption behavior of zeolites A and X, which are prepared from very cheap local Egyptian clay (kaolin), with respect to Cu(2+), Cd(+2), Cr(+2), Ni(+2) and Zn(2+) has been studied. The batch method has been employed, using metal solutions ranging from 100 to 400 mg/L. The distribution coefficients (K(d)) and adsorption percent were determined for the adsorption system as a f...
After kaolin treatment of fetal rabbit serum, 7S antibody titers were reduced more than 19S titers. This reduction was less when the kaolin treatment was performed at pH 9.0 than when it was performed at pH 7.3. A modification of the kaolin treatment of sera for use in the hemagglutination-inhibiting antibody titration, in which the hemagglutination reaction is performed at a neutral pH, is rec...
Abstract Hydrometer method is the standard that normally used to determine fine particle size distributions for soil classification purposes. This study aims develop new enable quick determination of silt-clay distribution compared hydrometer requires procedure pretreatment and additional 24 hours required complete test. The various samples were collected from seven different locations includin...
Kaolin has been widely used as an adsorbent to remove heavy metal ions from aqueous solutions. However, the lower heavy metal adsorption capacity of kaolin limits its practical application. A novel environmental friendly material, calcium alginate immobilized kaolin (kaolin/CA), was prepared using a sol-gel method. The effects of contact time, pH, adsorbent dose, and temperature on Cu2+ adsorpt...
The kaolinite of the Duikhala Deposite in Iraqi Western Desert underwent intercalation with potassium acetate (KAc) and was subsequently washing water several times. More than 70% achieved checked using X-ray diffraction (XRD) technique by observing a decrease peak intensity 7.2 Å appearance at 14 after two days intercalation. surface area cation exchange capacity were increased treated sample ...
