Adsorption of organic and inorganic arsenic from aqueous solutions using MgAl-LDH with incorporated nitroprusside

Autor: Gabriel Max Dias Ferreira, Anderson Dias, Guilherme Dias Rodrigues, Keirom Osmany Nàjera Navarro, Gabriella Alexandre Borges, Kisla P. F. Siqueira, Silvia Juliana Barros e Silva, Aparecida Barbosa Mageste

Publikováno v: Journal of Colloid and Interface Science. 575:194-205

An evaluation was made of the use of MgAl-LDH with incorporated nitroprusside as an adsorbent to remove inorganic arsenic (As(III) and As(V)) and organic arsenic (DMA) from aqueous matrices. The material was synthesized by the co-precipitation method

Extraction of arsenic(III) in aqueous two-phase systems: A new methodology for determination and speciation analysis of inorganic arsenic

Autor: Aparecida Barbosa Mageste, Betânia A. de Araújo Faria, Leandro Rodrigues de Lemos, Guilherme Dias Rodrigues, Roberta C. Assis, Claudia L. Caldeira

Publikováno v: Microchemical Journal. 147:429-436

This work utilizes the liquid–liquid extraction technique of aqueous two-phase systems (ATPS) formed by a polymer and electrolyte to develop a novel methodology for the extraction, determination, and speciation analysis of inorganic arsenic. To opt

Phase Diagrams, Densities, and Refractive Indexes of Aqueous Two-Phase Systems Comprising (F68, L64, or PEO1500) + (Ammonium, Sodium, or Potassium Thiocyanate Salts) + Water: Effect of Cation and Type of Macromolecule

Autor: Beatriz M. Fontoura, Luis Henrique Mendes da Silva, Aparecida Barbosa Mageste, Vivianne Molica de Andrade, Maria C. Hespanhol, Leandro Rodrigues de Lemos

Publikováno v: Journal of Chemical & Engineering Data. 64:1991-1998

In extraction procedures, the more commonly used aqueous two-phase systems (ATPS) comprise mainly water, salt, and macromolecule, particularly the macromolecule poly(ethylene oxide) (PEO). However, one limitation of such ATPS is their capacity to sep

Liquid–Liquid Equilibrium of Aqueous Two-Phase Systems Composed of Nonionic Surfactant (Triton X-100, Triton X-165, or Triton X-305) and Choline Chloride

Autor: Gabriel Max Dias Ferreira, Guilherme Dias Rodrigues, Aparecida Barbosa Mageste, Leandro Rodrigues de Lemos, Silvia Juliana Barros e Silva

Publikováno v: Journal of Chemical & Engineering Data. 64:1632-1639

The study of aqueous two-phase systems (ATPSs) formed by ionic liquids based on the choline cation and nonionic surfactants has received attention in recent years because of the biodegradability and nontoxicity of their components. In this work, liqu
