Title: MAGNETIC NANOMATERIAL SOLID PHASE EXTRACTION AGENT, AND PREPARATION METHOD AND USE THEREFOR
Abstract:
A magnetic nanomaterial solid phase extraction agent used for absorbing phthalate organic pollutants in an environmental water sample, and a preparation method for said magnetic nanomaterial solid phase extraction agent. The magnetic nanomaterial solid phase extraction agent comprises magnetic silicon dioxide particles acting as cores, and a layered double hydroxide acting as a shell layer. The magnetic silicon dioxide particles are formed by coating magnetic nanocores with silicon dioxide. The layered double hydroxide shell layer is an Mg-Al double hydroxide.
