Determinação espectrofotométrica de sulfato em álcool etílico combustível empregando dibromosulfonazo III
A sensitive spectrophotometric method was developed for sulphate determination in automotive ethanol fuel. The method based on the reaction of the analyte with barium-dibromosulphonazo(III) complex lead to a decrease in the magnitude of the absorbance signals monitored at 649 nm. No sample pretreatm...
