TL;DR: Results presented in this paper are promising, in view of the successful encapsulation of ametryn in PHB or PHBV polymer microparticles, and indications that this system may help reduce the impacts caused by the herbicide, making it an environmentally safer alternative.
Journal ArticleDOI
Study of an organically modified clay: selective adsorption of heavy metal ions and voltammetric determination of mercury(II).
TL;DR: In this paper, a hydrophilic clay, Na-montmorillonite from Wyoming, USA, was rendered organophilic by exchanging the inorganic interlayer cations for hexadecyltrimethylammonium ions (HDTA), with the formulae of [(CH(3))(3)N(C(16)H(33))]) ion.
Journal ArticleDOI
Sorption and preconcentration of metal ions in ethanol solution with a silica gel surface chemically modified with benzimidazole.
TL;DR: The adsorption isotherms of MCl(2) and FeCl(3) by silica gel chemically modified with benzimidazole molecules were studied in ethanol solution and the material was applied in the preconcentration of metal ions from commercial ethanol normally used as engine fuel.
Journal ArticleDOI
Sorption and preconcentration of metal ions on silica gel modified with 2,5-dimercapto-1,3,4-thiadiazole
TL;DR: In this article, a modified silica gel was applied in the preconcentration of metal ions from commercial ethanol, normally used as engine fuel, which is suitable for quantifying these metals at low μgl−1 levels.
Journal ArticleDOI
Sorption and preconcentration of some heavy metals by 2-mercaptobenzothiazole-clay.
TL;DR: 2-Mercaptobenzothiazole loaded on previously treated clay was prepared, characterized and used for sorption and preconcentration of Hg(II, Pb(II), Zn( II), Cd (II), Cu (II) and Mn(II) from an aqueous solution.
