“…It was pointed out in literature that 8-hydroxyquinoline (oxine) has application for complexation of some of heavy metal ions [28,29], and it was pointed out the nitrogen atom of heterocyclic ring and adjacent phenolic -OH group suitable for chelation with heavy metal ions [30]. Our survey through literature did not show any application of Amberlite IR-120 modified with 8-hydroxyquinoline for the determination of transition and heavy metal ions.…”

In this study, a solid-phase extraction method combined with atomic absorption spectrometry for extraction, preconcentration, and determination of iron (Fe(3+)), copper (Cu(2+)), and lead (Pb(2+)) ions at trace levels in water samples has been reported. The influences of effective parameters such as flow rate, pH, eluent conditions (type, volume, and concentration), sample volumes, and interference of matrix ions on metal ions recoveries were studied. Under optimized conditions, the limits of detection were found in the range of 0.7-2.2 μg L(-1), while preconcentration factors for Fe(3+), Cu(2+), and Pb(2+) ions were found to be 166, 200, and 250, respectively, and loading half time (t (1/2)) values were less than 2 min for all analyte ions. The proposed procedure was applied for the determination of metal ions in different water samples with recovery of >94.4% and relative standard deviation less than 4.4% for N = 5.

“…The results are given in Table 1. The results showed that Na + , K + , Mg 2+ , Ca 2+ , Zn 2+ , Ni 2+ , Co 2+ , Al 3+ , Mn 2+ , CO 3 2-, SO 4 2-, PO 4 3-, Cl -and MnO 4 -had no obvious influence on the absorbance of analyte. Fe 3+ and Fe 2+ after their tolerance limits, have positive and negative interference effects, respectively.…”

A simple spectrophotometric method was optimized for the speciation vanadium using pyrocatechol violet as chelating agent. Vanadium(V) was determined by pyrocatechol violet at pH 3.0, whereas vanadium(IV) was simultaneously determined using same procedure after oxidation of vanadium(IV) by potassium permanganate. The linear range for vanadium(V) is 0.2-4.0 μg/mL with a detection limit of 0.038 μg/mL. The proposed spectrophotometric method was found selective for vanadium(V) with high tolerence limit of foreign ions. The proposed method was validated by standard addition method at different levels of both understudied species with >92 % recoveries in water, black pepper and coal samples.

“…The palladium nitrate solution of 1000 mg/L was prepared by dissolving 106.6 mg Pd (NO 3 ) 2 (Merck) in 50 mL of 0.1% (v/v) HNO 3 . A 1.0 mol/L solution of Mg(NO 3 ) 2 (Merck) was prepared by dissolving 14.8 g Mg(NO 3 ) 2 in 100 mL of deionized water [28]. All glassware and polyethylene bottles were kept overnight by soaking in 10% HNO 3 , and cleaned by rinsing repeatedly with ultrapure water prior to use.…”
