The behavior of N,N-dimethylphenyl-p-diamine (DMPD), N,N-diethylphenyl-p-diamine (DEPD), phenyl-p-diamine (PPD), p-aminophenol (PAP) and other three aromatic amines was investigated and the chemical parameters of proposed flow methods were optimized by applying central composite design. For each evaluated method the concentration of amine, Fe3+ and H2SO4 was optimized and after the evaluation of reagents addition order the flow parameters were independently ascertained. Analytical signal was strongly diminished in the presence of iodide for flow methods based on the reaction of sulfide with DMPD, PPD or DEPD while fluoridewas considered as an important interference for methods based on the reaction with PPD or PAP. The evaluated aromatic amines have permitted sulfide determination in a wide concentration range from 0.05 to 3.0 mg L−1 and limits of detection (3σ) varying from 18.8 to 51.0 μg L−1, for DEPD and PPD, respectively. The sensitivity of flow methods based on PPD and DMPD was higher even as PAP has permitted sulfide determination in a large sulfide concentration range. In addition, higher throughput was attained for DMPD method. The proposed methods were applied for sulfide determination in industrial wastewater and the obtained results were in agreement with reference method at 95% confidence level.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-05-31T19:46:44Z No. of bitstreams: 1 __ac.els-cdn.com_S002626...85453f62e887f15fe34a6ab349ab9.pdf: 411102 bytes, checksum: a274fd89854e726d54bc678d47e489cb (MD5)Made available in DSpace on 2012-05-31T19:46:44Z (GMT).
