Determination of Ni(II) in Water Using Nanometer Attapulgite Adsorption via FAAS
Keyword(s):
nanometer attapulgite is a fine adsorptive reagent to Ni(II) in specific pH,adsorbent dosage , surging and depositing time, hydrochloric acid concentration, elution volume , surging and depositing time for the recovery and static adsorptive capability. The experimental results show that Zn(II)、Co(II)、K+、Cu(II)、Na+、Mn(II)、Pb(II)、Hg(II) 、SiO32- 、WO42- 、MoO42- 、HPO42-、VO3- didn’t interfere the adsorption to Ni(Ⅱ). the linear range is 0.10~1.5ug/mL, the regression equation is A=0.0476C+0.0084 r=0.9996 .the detection limit is 0.190μg/mL for Ni(II),recovery is 86.7.5%-102.5%. This method can be used to the determination of Ni(II) in environmental water.
