Cleavable porous silicon based hybrid material for pre-enrichment of trace heavy metal ions

Publication year: 2012 Source: Applied Surface Science, Available online 13 February 2012 Shaoyuan Li, Wenhui Ma, Yang Zhou, Yanfeng Wang, Wei Li, … The paper reports on the preparation of the cleavable porous silicon (PSi) based hybrid material and application in pre-enrichment of trace heavy metal ions. The cleavable groups (benzimidazoledithio) were grafted on the PSi surface by a stepwise covalent process
