  j-acid
A simple spectrophotometric determination of phorate using J-acid

Color reactions of rare earths with high sensitivity and selectivity based on the formation of polycomponent complexes in the system of RE-amino-J acid chlorophosphonazo-TPC-C2H5OH have been investigated. In acid medium (0.1-0.3N HCl) in the presence of cationic surface-active agent TPC and ethyl alcohol, amino-J acid chlorophospho-nazo with rare earths reacts to form blue colored complexes.The maximum absorption of the complex of cerium was observed at 695nm. The molor absorptivity of the complex of cerium was 2.01×105 1-1. mol-1. cm-1. Under the same condition, heavier rare earths do not convert to corresponding complexes. The color remains stable for 1 hr. Beer's law is obeyed over the range 0-12 μg/25ml Ce. Many cations and ani-ons do not interfere. The method has been applied to the determination of RE in steel and the results of determination are found to be satisfactory.

In this paper the solid coordination compounds composed of lanthanum, praseodymium, europium or yttrium with alizarin red-S(Na_3RE(Ars)·2H_2O) or J-acid(REJ_3·3H_2O) or both of them(NaRE(Ars)J·nH_2O have been prepared, and their infrared and electronic spectra, nuclear magnetic resonance, thermal analysis, electrophoresis, electric conductance, fluorescence spectra and solubility in various solvents have been investigated. Na_3RE(Ars)·2H_2O was prepared through the addition of rare earth chloride and alizarin red-S into the HAc-NaAc buffer solution. Na_3RE(Ars)·2H_2O is soluble in dimethylsulfoxide and water, but insoluble in nonpolar and less polarized solvents, while REJ_3·3H_2O and NaRE(Ars)J·nH_2O are only sparingly soluble in highly polarized solvents. As to the IR spectra, it shows that: (1) In the spectrum of alizarin red-S, strong absorption peaks corresponding to the hydroxide radical and association of hydroxide with water appear, while in the spectra of these rare earth coordination compounds only a broad absorption peak corresponding to the hydroxide radical of water is present. (2) In the spectrum of alizarin red-S, the absorption peak of carboxyl group appears at 1666 cm~(-1), and that of hydrogen bond at 1332cm~(-1), but in the spectra of these rare earth coordination compounds, the former appears at lower wave number and the latter at higher wave number. Based on the testing results, the composition and structure of these compounds have been proposed.
