In the present work four different analytical methodologies were studied for the determination of iron and titanium in Portland cement. The cement samples were dissolved with hot HCl and HF, being compared Fe and Ti concentrations through four analytical methods: molecular absorption spectrophotometry using the reagents 1,2-hydroxybenzene-3,5-disulfonic acid (Tiron) and the 5-chloro-salicylic acid (CSA), inductively coupled plasma atomic emission spectrometry (ICP-AES) and flame atomic absorption spectrophotometry (FAAS). In the spectrophotometric determinations were studied pH conditions, reagents addition order, interferences, amount of reagents, linear range and stability of the system. In the techniques of ICP-AES and FAAS were studied the best lines, interferences, sensibility and linear range. The obtained results were compared and the agreement was evaluated among the methods for the determination of the metals of interest.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-11-25T19:41:40Z No. of bitstreams: 1 4281.pdf: 47758 bytes, checksum: 30d179a206d48c8aa8e36edb2a7c2cb3 (MD5)Made available in DSpace on 2011-11-25T19:41:40Z (GMT).
