“…The application of a very sensitive and selective on-line flow-injection method for the determination of thorium(IV) after preconcentration in a minicolumn with N-benzoylphenylhydroxylamine-impregnated XAD-4 resin to biological samples has been described [38]. Sample rates of 40 and 11 h , respectively [38].…”

The discovery of new drugs, especially when many samples have to be analyzed in the minimum of time, demand the improvement or development of new analytical methods. Various techniques may be employed for this purpose. In this context, this chapter gathers the collection of paper and represents the review of past work on spectrophotometric technique coupled to a continuous flow system to determine low concentrations of several chemical species in different kinds of pharmaceutical and biological samples. A short historical background of the flow-injection analysis technique and a brief discussion of the basic principles and potential are presented. Part of this chapter is devoted to describing the sample preparation techniques, principles, and figures of merit of analytical methods. Representative applications of flow-injection spectrophotometry to pharmaceutical and biomedical analysis are also described.

“…Moreover, XAD-4 resins impregnated with nalidixic acid (HNA) were also successfully used for the preconcentration of U(VI) prior to their determination by an FI online spectrophotometer [125]. By means of XAD-4 containing N-benzoylphenylhydroxylamine or oxytetracycline, Th(IV) can also be selectively determinated by the FI online method [126,127].…”

The recovery and separation of metals from aqueous solutions is one of the research hotspots in hydrometallurgy, environment protection, analytical chemistry, etc. Much attention has been paid to solvent-impregnated resins (SIRs) since these were firstly proposed for the extraction of metals. SIRs are characterized by high efficiency and selectivity, convenient preparation, and easy operation because they combine the unique advantages of solvent extraction and ion exchange. The preparation and features of SIRs are summarized and their applications in the extraction of various metals from solutions are reviewed. In addition, the equilibrium, thermodynamics, and sorption kinetics of the metals onto SIRs are elucidated in detail.

“…BPA is proved to be efficient reagent in liquid-liquid extraction whose selectivity is determined which is strongly depends on the pH of the aqueous phase [32]. The most important parameter affecting the extraction is pH of the solution because the formation of the soluble metal complexes and their stabilities in aqueous solutions are strongly related to the pH of the medium.…”
