摘要: A solid-phase extraction method for separation and preconcentration of Ir(IV) ion by using activated carbon cloth (ACC) has been presented. as their 1-(2-pyridylazo) 2-naphtol (PAN) chelate was adsorbed on ACC at pH 2.0 eluted from with acidic dimethylformamide (DMF). The concentration determined 536 nm Ir(IV)–PAN complex UV–vis spectrophotometer. analytical parameters including pH, sample eluent flow rates, amount PAN, type, concentration, volume were optimized. effects foreign ions the recoveries iridium also investigated. factor calculated 60. limit detection (LOD) quantification (LOQ) found 0.039 0.129 μg L−1, respectively. applied to soil water samples determination.
