| Summary: | Sample pretreatment is an essential step in the analytical process. Solid phase extraction (SPE) procedures are widely used for clean-up and enriching analytes in sample preparation due to the complex sample matrix and low concentration level of target compounds. The sorbent is the critical part and plays a vital role in the SPE process. The combination strategies of green sample preparation (GSP) with sorbents have been taken seriously to establish high-performance and environmental-friendly SPE methods. This work mainly reviewed the capacity of different functional materials to be used as SPE sorbents which fulfilled the GSP requirements, including metal-organic frameworks (MOFs), molecularly imprinted polymers (MIPs), natural products, and carbon-based materials. Advanced computer-assisted strategies for the synthesis and usage of green SPE sorbents are also overviewed. Finally, recent advanced applications of these green adsorption materials for SPE procedure were summarized. This review aims to retrace latest research of green sorbents-based SPE techniques under the perspective of GSP, suggesting the future synthesis and application of adsorption materials should pose the features of less reagent and energy usage, less labor and time consuming, and high extraction efficiency.
