Design of a novel microfluidic chip for measuring Aluminum(III) with Alizarin Red S as a reagent

Abstract

The research included the design of a microfluidic chip with two channels, one of which is 7 cm long and the other 6 cm, to be used for determination using the microfluidic injection system. It's a new, simple, sensitive, fast, and inexpensive method. The process depends on the reaction of Aluminum (III) with Alizarin Red S (ARS), spectrographically recorded at 481 nm

The calibration curve, dispersion coefficient, repeatability, interferences, and applications were studied where the linearity ranged between (1.0 - 10.0)
