Flow injection determination of iron ions with green tea extracts as a natural chromogenic reagent
A green chemistry system that utilizes natural extract as an alternative reagent for determination of metal ions has been investigated. The extract of green tea, a common beverage, is used for quantification of iron. The green tea extract was prepared in acetate buffer pH 4.8 and could be used witho...
