“…O monitoramento espectrofotométrico de SO 2 pode ser alcançado através de sua conversão a um cromóforo produzido com o corante [15][16][17][18][19][20]. De forma similar, a aplicação de protocolos experimentais apropriados, capacita a análise de distintos compostos, tais como, ácido pícrico, sacarina, fenil butazona e a droga Probenecida [21], metanol [22], bromato [23,24], brometo [25], SO 3 -2 [26,27], Formaldeido [28][29][30][31][32][33][34][35], H 2 S [36][37][38], o pesticida organoclorado endosulfano [39], substancias tensoativas [40], os metais ouro [41] e Paládio [42].…”

O corante pararosanilina (P) é um pigmento que apresenta um relevante papel na análise de substâncias química e bactérias do tipo Gram positivo e negativo, além de outros microorganismos. Os ensaios potenciométricos de P mostraram que o corante é um ácido monoprótico e fraco (pKa= 8,78); enquanto a espectrofotometria permitiu estimar seu coeficiente de absortividade molar (ε) igual a 1,48x10(4) mol-1 cm-1 L. A curva analítica para a determinação de P apresenta linearidade entre 7,36x10-6 a 7,36x10-5 mol L-1 e a metodologia foi aplicação em amostras biológicas.

“…Konig and Crowell have found that thioglycolic or thiomalic acids give yellow' colors wflth as little as 0.05 microgram of palladium (196), and that phenoxathiin forms an addition complex with palladium and can be used as a sensitive reagent for this metal (194). West and Amis found that pararosaniline hydrochloride is a very sensitive reagent for palladium and devised a specific test based on its use (399). Wrest and Tokos (400) suggested the use of brucine citrate for the detection of bismuth, and West developed a specific and sensitive test for copper using dithiooxamide with malonic acid as a conditioning agent (398).…”

MICROCHEMICALanalysis can be considered to include the sampling, separation, detection, and estimation of minute amounts of material, regardless of the techniques employed. Quite properly, emission spectroscopy, polarography, chromatography, and similar techniques, which are fields within themselves, fall under the broad classification of microchemistry. For the present paper, however, a limitation of scope is made to prevent overlapping with other reviews, and the reader is referred to such other reviews to complete the orientation on progress in the general field of microchemistrv.The review of inorganic microchemistrv does not include, except for isolated cases, papers on light microscopy, electron microscopy, nucleonics, polarography, fluorescence, or electro-

Pararosaniline dye (P) is a pigment which has a significant role in analysis of chemical substances and gram-positive and negative bacteria, as well as other microorganisms. Potentiometric essays of P have shown that the colorant is a weak monoprotic acid (pKa= 8,78);and the spectrophotometry allows to estimate its molar absorption coefficient as 1,48x104 mol-1 cm-1 L. The analytical curve for a determination of P has linearity between 7,36x10-6 and 7,36x10-5 mol L-1, and the methodology was application in biological samples.
