Use of dye aggregation phenomenon for spectrophotometric and SIA-LAV determination of bismuth(III) as a specific ion association complex between tetraiodobismuthate and Astra Phloxine
TL;DR: In this paper, a simple, highly sensitive and selective non-extraction spectrophotometric and sequential injection analysis with lab-at-valve (SIA-LAV) methods for the determination of bismuth(III) have been developed based on the formation of a specific ion association complex (IA) between tetraiodobismuthate (III) anion and the polymethine dye Astra Phloxine (AP).

Normal and second derivative spectrophotometric determination of niobium using solid phase extraction technique
TL;DR: In this paper, a solid phase extraction (SPE) method using freshly precipitated microcrystalline naphthalene as an adsorbent has been developed to separate and preconcentrate trace amount of niobium from aqueous samples for the detection by normal and second derivative spectrophotometry.
