Journal ArticleDOI

Immobilization of ethylenesulfide on silica surface through sol–gel process and some thermodynamic data of divalent cation interactions

Claudio Airoldi, +1 more
- 30 Apr 2001 - 
TL;DR: In this article, the silylant precursor agent 3-aminopropyltrimethoxysilane (APTS) reacted with ethylenesulfide to yield 2-{2-{3-(trimETHoxysilyl)propylamino}ethylthio}ethanethiol, which was anchored on silica gel by using the sol-gel process.
Journal ArticleDOI

Adsorption and separation of cations on chemically modified silica gel synthesised via the sol–gel process

Alexandre G.S. Prado, +2 more
- 01 Jan 2001 - 
TL;DR: In this paper, the reaction of ethylene sulfide with 3-aminopropyltrimethoxysilane resulted in a new silylating agent, which was anchored onto a silica surface via the sol-gel procedure.
Journal ArticleDOI

Silylated calcium phosphates and their new behavior for copper retention from aqueous solution

Oberto G. da Silva, +2 more
- 05 Jul 2007 - 
TL;DR: Anhydrous calcium phosphate (CaP) was modified by surface silylation using three organosilanes (H3CO)3SiR, where R corresponds to the organic moieties CH2CH2CH 2NH2, CH 2CH2 CH2NHCH2NH2, and CH 2 CH2H2NH 2NH 2, originating nanomaterials named CaPSil1, CaPSili2, and CaPSIL3 as mentioned in this paper.
Journal ArticleDOI

O relevante papel do agente sililante na modificação de superfícies de polímeros

Luiza N.H. Arakaki, +1 more
- 01 Apr 1999 - 
TL;DR: The applicability of the silylant agents of the general formula Y3Si-R-X, depends on the reactivity of Y group (halide or alcoxide) attached to silicon and the organic function X in the extreme position of the chain this article.
Journal ArticleDOI

New thiol adsorbent grafted on silica gel: synthesis, characterization and employment for heavy metal adsorptions

Luiza N.H. Arakaki, +6 more
- 25 Mar 2003 - 
TL;DR: This material was characterized by elemental analysis, IR spectroscopy, thermogravimetry, solid state 13C and 29Si NMR, and surface area measurement and employed as adsorbents for divalent heavy cations from aqueous solutions at room temperature and the isotherms were adjusted to a modified Langmuir equation.
