Sequential spectrophotometric determination of chromium(III) and chromium(VI) using flow injection analysis
(1985-12-01)
A flow injection analysis (FIA) procedure for the speciation of Cr(III) and Cr(VI) using the 1,5-diphenylcarbazide (DPC) method is presented. As Cr(III) does not interfere in the Cr(VI) - DPC reaction, both Cr(VI) and total ...
Sequential injection analysis (SIA) and response surface methodology: A versatile small volume approach for optimization of photo-Fenton processes
(ELSEVIER SCIENCE BV, 2009)
Optimization of photo-Fenton degradation of copper phthalocyanine blue was achieved by response surface methodology (RSM) constructed with the aid of a sequential injection analysis (SIA) system coupled to a homemade ...

Applying sequential injection analysis (SIA) and response surface methodology for optimization of Fenton-based processes
(ELSEVIER SCIENCE BV, 2009)
This work presents the use of sequential injection analysis (SIA) and the response surface methodology as a tool for optimization of Fenton-based processes. Alizarin red S dye (C.I. 58005) was used as a model compound for ...
Development of a sequential injection-square wave voltammetry method for determination of paraquat in water samples employing the hanging mercury drop electrode
(SPRINGER HEIDELBERG, 2010)
This work describes the development and optimization of a sequential injection method to automate the determination of paraquat by square-wave voltammetry employing a hanging mercury drop electrode. Automation by sequential ...
A análise por injeção sequencial (SIA): vinte anos em uma perspectiva brasileira
(Sociedade Brasileira de Química, 2010)
The year of 2010 marks the 20th anniversary of the development of Sequential Injection Analysis (SIA) by Ruzicka and Marshall. Considered the second generation of the flow injection methods, this article briefly describes ...
