This review covers a relatively mature area of atomic spectrometry, hence there are fewer
new developments than in other research fields. The review should be read in conjunction …

Amino-functionalized titanosilicate materials were prepared as an alternative for developing
efficient adsorbents of azo dyes. Functionalization of the titanosilicates with ethylenediamine …

This work describes the synthesis and characterization of 2-aminothiazole modified silica
gel (SiAT) and the studies of adsorption and pre-concentration (in batch and using a flow …

Silica gel chemically modified with 2-Aminotiazole groups, abbreviated as SiAT, was used
for preconcentration of copper, zinc, nickel and iron from kerosene, normally used as a …

The use of materials such as organofunctionalized silica for application in solid phase
extraction (SPE) allows the preconcentration of several ions, including Pt, and subsequent …

The present work reports the effectiveness of a 2D imprinting method based on a surface
imprinting technique for the development of a selective and sensitive flow sorbent …

The hybrid 3-(1, 4-phenylenediamine) propylsilica xerogel was obtained starting from two
different organic precursor quantity (5 and 8 mmol) to 22 mmol of TEOS, in the synthesis …

Cadmium is considered a potentially toxic element, since it doesn't perform any biological
function and is highly cumulative. This element is usually found in environmental samples in …

O composto cristalino lamelar fenilfosfonato de cálcio (CaPP) foi preparado e intercalado
com o ácido m-aminobenzóico (MABA) eo ácido p-aminobenzóico (PABA), resultando nos …

A novel column solid phase extraction procedure was developed for the determination of Ni
(II), Cu (II) and Zn (II) in water samples using newly synthesized reagent 1-(2-hydroxy-5 …
