ABSTRACT. A new sorbent was prepared using alumina and 5-Br-PADAP, and its adsorption ability for the removal of Ni(II) and Pd(II) from different waters was investigated. The procedure is based on retention of the analytes on the alumina load with 5-Br-PADAP at pH ~ 6. The separation/preconcentration conditions for the quantitative recoveries were investigated. The limit of detections (LOD) based on three times the standard deviations of the blank, were 0.187 and 0.253 ng mL -1 for Ni(II) and Pd(II), respectively. Obtained sorption capacities for 1 g sorbent were 6.0 mg Ni(II) and 11.0 mg Pd(II). The linearity was maintained in the concentration range of 0.625 to 6.0 ng mL -1 for Ni(II) and 0.416 to 7.0 ng mL -1 for Pd(II) in the original solution. Eight replicate determinations of a mixture containing 2.0 µg mL -1 each of the elements in the final solution gave relative standard deviation of ±0.82 and ±1.12% for Ni(II) and Pd(II), respectively. The proposed method was successfully applied to the determination trace amounts of Ni(II) and Pd(II) in the surface water samples.

“…A quantitative retention is not obtained when the amount of sorbent is less [41]. On the other hand, an excess amount of resin prevents the elution of the retained chelates by a small amount of eluent quantitatively [41]. For this purpose, different amounts of the sorbent (10-200 mg) were examined.…”

“…Interference from this ion is probably that it retains strongly on the resin than copper. However, the concentration of iron in drinking water is normally lower than 5 mg/L [29] and there is no interference at ten-fold of the concentration of copper.…”

Optimization of a new resin, Amberlyst 36, as a solid-phase extractor and determination of copper(II) in drinking water and tea samples by flame atomic absorption spectrometry A new simple and reliable method has been developed to separate and preconcentrate trace copper ion in drinking water and tea samples for subsequent measurement by flame atomic absorption spectrometry (FAAS). The copper ions are adsorbed quantitatively during passage of aqueous solutions through Amberlyst 36 cation exchange resin. After the separation and preconcentration stage, the analyte was eluted with a potassium cyanide solution and determined by FAAS. Different factors including pH of sample solution, sample volume, amount of resin, flow rate of aqueous solution, volume and concentration of eluent, and matrix effects for preconcentration were examined. The analytical figures of merit for the determination of copper are as follows: analytical detection limit (3 r), 0.26 lg/L; precision (RSD), 3.1% for 100 lg/L; enrichment factor, 200 (using 1000 mL of sample solution and 5 mL of eluent); time of analysis, 3.5 h (for obtaining enrichment factor of 200); capacity of resin, 125 mg/g. The method was applied for copper determination by FAAS in tap water, commercial natural spring water, commercial treated drinking water, and commercial tea bag sample. The accuracy of the method is confirmed by analyzing tea leaves (GBW 07605). The results demonstrated good agreement with the certified values.

A simple field sampling-preconcentration method for zinc determination in seawater is described. Seawater was collected in situ by pumping it through a minicolumn packed with a chelating resin (Chelite P) connected to a field flow preconcentration system (FFPS). These packed minicolumns retain the dissolved zinc, and once are loaded with the analyte, they are returned to the laboratory where they are sequentially inserted into a flow injection system for on-line zinc elution with diluted hydrochloric acid and flame atomic absorption spectrometric detection. A factorial design has been used to optimize the FFPS and the flow injection elution process. The proposed method has a linear calibration range from 0.07 to at least 9.4 µg L -1 of zinc, with a detection limit of 0.02 µg L -1 and a throughput of 26 samples h -1 . Validation was carried out against certified reference water samples. This procedure has been successfully applied to the determination of Zn in seawater samples from Galicia (Spain).
