eurjchem-1587	Payehghadr, Mahmood	Flame atomic absorption determination of ultra-trace zinc in environmental samples after pre-concentration by solid phase extraction	2017	5	.pdf	application/pdf	3672	217	66	In the present study, a simple separation‐pre‐concent‐ ration method for atomic absorption spectrometric determi‐ nation of Zn2+ ion in water samples and two agricultural plants samples after extraction of N,N´‐bis(salicylidene)1,8‐diamino‐ 3,6‐dioxaoctan Schiff base ligand (L) (Figure 1) complexes of Zn2+ ion on an octadecyl silica disk has been established. Effect of flow rate and pH The effect of flow rates of the sample and stripping solutions from the modified membrane disk on the retention and recovery of Zn2+ ion was investigated.	cache/eurjchem-1587.pdf	txt/eurjchem-1587.txt
