Surface modification of sepiolite particles with polyurethane and polyvinyl alcohol

Application of sepiolite in clarification of pomegranate juice: changes on quality characteristics during process

“…Sepiolite with a formula Mg 8 Si 12 O 30 (OH) 4 (OH 2 ) 4 .nH 2 O( n = 6–8) is a natural fibrous phyllosillicate clay mineral (Sabah et al ., ; Miura et al ., ). The structural and morphological characteristics of sepiolite result in its specific physicochemical properties such as high porosity, specific surface area and adsorption capacity (Suárez & García‐Romero, ; Alan & İşçi, ). In recent years, this clay has been used in food industry for removal of phosphorus from vegetable oil, enhancing decolorisation of crude palm oil and decolorisation of sugar juice (Ünal & Erdoğan, ; Sabah & Majdan, ; Tian et al ., ).…”

Modified nanosepiolite as an inexpensive support of tetraethylenepentamine for CO2 sorption

“…Its structure contains ribbons of a 2:1 phyllosilicate structure; each ribbon is linked to the next inversion of SiO 4 tetrahedral sheet with a set of Si-O bonds [31]. The complex ribbon layered structure involves blocks that make a capillary network of parallel channels.…”

Thermal Comparison of Montmorillonite / HEC and Sepiolite / HEC nanocomposites

“…The main characteristic bands of Sepiolite at 3684 cm -1 , 3550 cm -1 , 1693 cm -1 , and 1658 cm -1 , 1204 cm -1 , and 1022 cm -1 , 780 cm -1 , 691cm -1 , and 648 cm -1 , are ascribed to bending of Mg-OH, -OH stretching, OH bending, Si-O-Si bands, bending of Mg-Fe-OH and Mg-OH bending, respectively (Alan & Isci, 2014;S. Isci, 2015;Serna & Vanscoyoc, 1979).…”

“…HEC, like the other cationic polymers can interact electrostatically with charged surface of clay particles. (Alan & Isci, 2014;Bergaya et al, 2006;E. Isci & Turutoglu, 2011;S.…”
