Electrokinetic and adsorption properties of sepiolite modified by 3-aminopropyltriethoxysilane.
Surface modification of clay minerals has become increasingly important for improving the practical applications of clays such as fillers and adsorbents. An investigation was carried out on the surface modification of sepiolite with aminopropylsilyl groups in 3-aminopropyltriethoxysilane (3-APT). The zeta potential of the modified sepiolite suspensions was measured as a function of initial elec...
متن کاملMicrostructure 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 کاملAdsorption Isotherm and Kinetics Study: Removal of Phenol Using Adsorption onto Modified Pistacia mutica shells
Background and purpose: Phenol is an aromatic hydrocarbon and one of the banzan derivatives which has a higher dissolution rate in water. Therefore, it must be removed for water pollution prevention. The aim of this study was to investigate the possibility of Pistaciamuticabio mass as an alternative adsorbent for phenol removal from aqueous solution. Materials and Methods: The effect of variou...
متن کاملSolid-state Nuclear Magnetic Resonance Study of Sepiolite and Partially Dehydrated Sepiolite
The assignment of the Si CP/MAS-NMR spectrum of naturally-occurring sepiolite clay was re-examined using Si COSY and H-Si HETCOR pulse sequences. Each of the three main resonances at 92.1, 94.6 and 98.4 ppm has been attributed to one of the three pairs of equivalent Si nuclei in the basal plane, and the resonance at 85 ppm to Q(Si-OH) Si nuclei. On the basis of the COSY experiment, the resonanc...
متن کاملClinical and radiological study in sepiolite workers.
Radiological findings were evaluated on a mass survey (70 mm films) in four villages where mining and processing of sepiolite have occurred for more than 100 yr, together with a clinical and radiological study in 63 sepiolite trimming workers in Eskisehir, Turkey. Mineral fiber-related pleural diseases were not detected in those people who were exposed to sepiolite dust. Although pulmonary fibr...
