Surfactant-modified montmorillonite by benzyloctadecyldimethylammonium chloride for removal of perchlorate

N-[3-(Trimethoxysilyl)propyl] ethylenediamine Functionalized Saponite as Adsorbent of Nickel from Aqueous Solution

“…The double reflections may be the result of the possible conformation of organic compounds intercalated in clay in which the possible conformations include paraffinic, bilayer or pseudotrimolecular [15]. A similar trend was reported for surfactant-intercalated montmorillonite with cetyl trimethyl ammonium bromide(CTAB) and benzyloctadecyldimethylammonium chloride when the value of the surfactant molar ratio to cation exchange capacity was greater than 1 [16][17][18]. Specific peak at around 28 o correspond to 3.35Å found in SAP and EDASAP-1 correspond to the presence of elemental silica probably in the form of quartz in very small quantity is identified.…”

Effects of cationic surfactant on the bioaccumulation of polycyclic aromatic hydrocarbons in rice and the soil microbial community structure

“…CTMAB was reported to provide a certain amount of N for plant growth as an alkyl-substituted ammonium salt. 32 In the present study, the content of NH 4 + -N in the 150 CTMAB treatment was signicantly increased compared with that in the other treatments (Table S2 †), however, 150 mg kg À1 CTMAB did not signicantly promote the rice yield (p < 0.05).…”

Organoclays used as colloidal and rheological additives in oil-based drilling fluids: An overview

“…Murray (1999) reported that the CEC of Mt generally lied in the range of 60-100 cmol/kg. Some recent papers demonstrated higher CEC values which were more than 100 cmol/kg (He et al, 2010;Karaca et al, 2012;Sun et al, 2013;Fernández et al, 2014;Luo et al, 2015). An extremely high CEC of Mt was reported as 174 cmol/kg by Fernández et al (2014).…”
