Environmentally friendly nanoflower Al₂O₃@carbon spheres as adsorbent for dispersive solid-phase microextraction of copper and lead in food and water samples

Abstract

A fast and simple dispersive solid phase micro extraction method (d-SPµE) was described for the copper and lead determination in food, water, and sediments by using FAAS. Firstly, nanoflower Al2O3@carbonspheres...
