Reagents and Solutions

All solutions were prepared with distilled and deionized water (Milli-Q Plus, Millipore, Barueri, São Paulo, Brazil). The calibration solutions were prepared after successive dilutions of the stock standard solutions (Merck, Darmstadt, Germany). For Fe and Zn, the concentrations varied from 0.25 to 8 and from 0.2 to 1.5 mg/L, respectively. Due to the expected low Cd and Pb concentrations, the calibration solutions varied from 5 to 25 and from 100 to 500 μg/L, respectively.

Reagen dan Solusi

Semua solusi disiapkan dengan suling dan air deionisasi (Milli-Q Plus, Millipore, Barueri, São Paulo, Brazil). Solusi kalibrasi disusun setelah pengenceran berturut solusi standar saham (Merck, Darmstadt, Jerman). Untuk Fe dan Zn, konsentrasi bervariasi 0,25-8 dan 0,2-1,5 mg / L, masing-masing. Karena konsentrasi Cd dan Pb rendah yang diharapkan, solusi kalibrasi bervariasi dari 5 sampai 25 dan 100-500 mg / L, masing-masing.
