Determination of anions by ion chromatochraphy in water samples of Baghdad city
Determinations of common anions by IC methods in Baghdad were carried out in this investigation. The optimum values of the instrumental parameters were reached best in relative standard deviation (RSD), correlation coefficient (r2) and method detection limits (MDLs) and other parameters to proving the precision and accuracy of this method. Both peak height (PH) and peak area (PA) were used for the evaluation of the IC...

Vitamin B12 models: Synthesis and characterization of cyano bridged dicobaloximes and antimicrobial activity
Reactions of the cyanide complexes of the type Co(CN)(DH)2L moiety (where L= thiourea, acetamide, formamide, semicarbazide, pyrazole and aniline; DH = dimethylglyoxime) with the corresponding benzyl(aqua)cobaloxime PhCH2Co(DH)2OH2 gives a series of homometallic cyano-bridged compounds of the type PhCH2Co(DH)2CNCo(DH)2L. All these complexes have been synthesized and characterized by means of IR,...
