· 2mercaptobenzothiazole (MBT) is a constituent of certain flotation collectors, and there is a need for determination of MBT residuals in flotation plant liquors. UV absorbance measurements at 310 nm in alkaline solution showed that Beer's law held up to 12 ppm MBT. At 323 nm in acid solution Beer's law held up to 9 ppm MBT.

flotation spectrophotometric determination
Flotation spectrophotometric determination of aluminium . Aluminium was determined in a weakly alkaline medium by reaction with alizarin at trace level. Flotation of the complex was carried out with heptane followed by dissolution in N Ndimethylformamide (DMF) for subsequent spectrophotometric determination. The molar absorptivity was 105 mol1 cm1 at 518 nm. Beer s law was obeyed in ...
