Microstructure and chemical changes of sepiolite and vermiculite clays on the effect of elements adsorption
One of the applicable methods to control the pollution of heavy metals is the use of an adsorbent mineral. The aim of this research is to investigate the effect of Nickel and Zinc elements on microstructure properties of sepiolite and vermiculite clay minerals. To address the absorption experiment studies, four treatments (vermiculite, vermiculite + sand soil, sepiolite and sepiolite + sand soi...
متن کاملInfluence of Mechanical and Chemical Treatment of Vermiculite on Resulting Antibacterial Activity of Organovermiculites
Grinding and acid treatment of clays modifies their surface and can significantly affect their resulting behaviour. The Mg-vermiculite was milled for 20 min using planetary ball mill Retsch. After sieving, fraction 40 μm was obtained (sample V). Half of this fraction was milled again in vertical jet mill Sturtevant (sample Vj). Parts of these milled samples were treated with HCl for 5 hours a...
متن کاملInteraction of aminotriazole with montmorillonite and Mg-vermiculite at pH
The interaction of aminotriazole (AMT) at pH 4 on Wyoming montmorillonite (mainly with Na ions) and Mg-vermiculite has been studied by X-ray diffraction and infrared spectroscopy. The AMT is adsorbed on montmorillonite in the cationic form by cation exchange. The amount of pesticide adsorbed was 71 mEq/100 g, which comprises *91% of the CEC of this sample (78.2 mEq/100 g). Saturation was reache...
متن کاملSynthesis, characterization and properties of polyaniline/expanded vermiculite intercalated nanocomposite.
The synthesis characterization and conductivities of polyaniline/expanded vermiculite intercalated nanocomposite are presented in this paper. The conductive emeraldine salt form of polyaniline is inserted into the interlayer of expanded vermiculite to produce the nanocomposite with high conductivity. The structures and properties are characterized by transmission electron microscopy x-ray diffr...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
