文摘

A mesoporous silica-grafted graphene oxide (GO-SBA-15) was synthesized as a sorbent material. A FI based on on-line SPE coupled with SCGD-AES was developed to detect Pb(II). Sensitive detection of Pb(II) was achieved with a DL of 0.91 μg L− 1. The method was validated by certified reference material and applied to real sample.
