It has been shown that the temporal behavior of the outcome intensity obeys a certain law: ${{\text{D}}_{{\text{SD}}}}{\text{ }} = {\text{ }}1.3193{\text{ }}

Eyes of covalent organic frameworks: cooperation between analytical chemistry and COFs Rev. Anal. Chem. (IF 4.3) Pub Date : 2019-03-26 Hao Guo, Longwen Zhang, Rui Xue, Baolong Ma, Wu Yang
Abstract Covalent organic frameworks (COFs) are a class of porous organic crystal materials. Since Yaghi and co-workers reported the first COF material in 2005 (Côté, A. P.; Benin, A. I.; Ockwig, N. W.; O’Keeffe, M.; Matzger, A. J.; Yaghi, O. M. Science2005, 310, 1166–1170), COFs have shown great potential and research value in many fields, for instance, gas storage and separation, photoelectric function

Application of a xanthene dye, eosin Y, as spectroscopic probe in chemical and pharmaceutical analysis; a review Rev. Anal. Chem. (IF 4.3) Pub Date : 2018-06-13 Sayed M. Derayea, Dalia M. Nagy
Abstract Eosin Y (EY) is an acidic xanthene dye which is mainly used in food stuff and biological staining. Various analytical methods have been reported for the utility of this dye in the quantitative determination of several pharmaceutical compounds, heavy metals in addition to some surfactants and proteins. Most of the applied methods were based on the formation of association complexes between

Micelle-enhanced flow injection analysis Rev. Anal. Chem. (IF 4.3) Pub Date : 2018-04-10 Dalia T. Abdeldaim, Fotouh R. Mansour
Abstract Surface-active agents are organic compounds of amphiphilic nature. When the concentration of surfactants is higher than a certain value, the monomers adhere to form well-defined aggregates known as micelles. These micelles have been employed in flow injection analysis (FIA) for various purposes. In chemiluminescence-based FIA, micelles can improve sensitivity by changing the chemical structures
