An amplitude-modulated flow analysis coupled with lock-in detection is proposed for the determination of trace phosphate. The flow rate FS of sample solution is varied in response to a periodic signal...
Platinum(IV) can be determined spectrophotometrically with 5-chloro-2-hydroxythiobenzhydrazide on extraction into molten naphthalene from the aqueous phase with pH 2.2 − 6.0. Beers law is obeye...
A sensitive surfactant-mediated extractive spectrophotometric method has been developed, based on the reaction of ferric iron with sulfide to form ferrous iron and its subsequent reaction with ferricy...
A new reagent, 4-benzyl-1-piperazineglyoxime(BPGH2), was synthesized and used for developing a simple and rapid extractive method for the spectrophotometric determination of nickel. This method is bas...
In this study, waste water drains and produced phosphate fertilizers of conventional wet-process (hemihydrate) phosphoric acid and phosphate fertilizer plants were investigated to determine the averag...
