Adsorption of di-2-pyridyl ketone salicyloylhydrazone on Amberlite XAD-2 and XAD-7 resins: Characteristics and isotherms
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
The adsorption of DPKSH onto Amberlite XAD-2 (styrene resin) and XAD-7 (acrylic ester resin) has been investigated, at (25 +/- 1)degrees C and pH 4.7. The experimental equilibrium data were fitted to the Langmuir, Freundlich, ...

Preconcentration and Determination of Copper and Zinc in Natural Water Samples by ICP-AES After Complexation and Sorption on Amberlite XAD-2
(Journal of the Brazilian Chemical Society, 1998)
The present paper describes a procedure for separation, preconcentration and sequential determination of trace amounts of copper and zinc in natural water samples, by Inductively Coupled Plasma Atomic Emission Spectrometry ...
Copper, zinc and manganese determination in saline samples employing faas after separation and preconcentration on Amberlite XAD-7 and Dowex 1x-8 loaded with Alizarin Red S
(2004)
Two procedures have been proposed and compared for separation and preconcentration of trace amounts of manganese, copper, and zinc in saline samples. The procedures are based in the use of Amberlite XAD-7 and an anion-exchanger ...
An automated on-line flow system for the pre-concentration and determination of lead by flame atomic absorption spectrometry
(2001)
The use of Amberlite XAD-2 modified by 2-(2-benzothiazolylazo)-2-p-cresol (BTAC) as a sorbent in an on-line pre-concentration system for lead determination has been proposed. The procedure is based on the sorption of ...
