“…[20][21][22][23] Recently, a number of kinetic methods which were developed for determination of trace Cu(II) concentration have been reported. [21][22][23][24][25][26][27][28] Flow techniques are widely used in chemical analysis due to its many advantages, such as low volumes of sample and reagents (mL scale), greater reproducibility, and the possibility of measurement without the need to attain the nal equilibrium state. Multisyringe ow injection analysis (MSFIA) is a ow technique that includes the advantages of ow injection analysis (FIA), in terms of efficiency of mixing, and of sequential injection analysis (SIA) with regard to robustness and versatility.…”
