First, an effective pre-concentration of penicillamine was done via Fe3O4NPS. Then, a simple, rapid and sensitive spectrophotometric method is described for the determination of penicillamine by 2, 6-dichlorophenolindophenol (2, 6-DCPIP), as the chromogenic agent in bulk drug and formulations. It produces a bluish green coloured compound with maximum absorbance 610 nm. Beer’s law was obeyed […]
