Preconcentration and separation of trace amount of copper (II) on N1, N2-bis(4-fluorobenzylidene)ethane-1,2-diamine loaded on Sepabeads SP70

Preconcentration and determination of iron and copper in spice samples by cloud point extraction and flow injection flame atomic absorption spectrometry

“…The pH plays a unique role on metal-chelate formation and subsequent extraction [5][6][7][8]. Separation of metal ions by cloud point method involves the prior formation of a complex with sufficient hydrophobicity to be extracted into the small volume of surfactant-rich phase.…”

“…Due to these reasons, the accurate and precise determinations of trace metals are important for analytical chemists [5][6][7][8]. Because of its experimental rapidity, simplicity, and wide application, flame atomic absorption spectrometry is the one of the most widely applied methods those are based on spectrometry.…”

Diaion HP-2MG modified with 2-(2,6-dichlorobenzylideneamino) benzenethiol as new adsorbent for solid phase extraction and flame atomic absorption spectrometric determination of metal ions

“…In this regard, various support in our laboratory applied for the preconcentrationseparation of heavy metal ions. [11][12][13][14][15][16][17][18] This research focuses on the modification of Diaion HP-2MG with 2-(2,6-dichlorobenzylideneamino)-benzenethiol (DCBABT) and its efficient application to enrich and preconcentrate understudy metal ions. To obtain maximum recoveries for understudy metal ions, the influence of variables like pH, amount of DCBABT, condition of eluent and flow rates on method performance was examined.…”
