Over the last decade, significant progress has been made in the design, synthesis and use of hierarchically porous materials in areas ranging from nanoscience to catalysis, separation, energy, life science and other applications. These materials are comprised of a multimodal hierarchically porous structure made of interconnected pores with different lengths ranging from micro (˂2nm), meso (2–50nm) to macro pores (˃50 nm). In solid phase extraction techniques, the choice of the sorbent is a key point because it can control the analytical parameters such as selectivity, affinity and capacity. For this purpose, new sorbents based on activated carbon, metal oxide nanoparticles, hexagonally ordered silica material, polymers and molecular-imprinted polymers have recently appeared to separation sorbents. With attention to above details, our researche group focuses on investigate new application of hierarchically structured porous materials for analytical separation methods. So, new ordered porous materials based on silica products, carbon structures, molecular-imprinted polymers, layered double hydroxides, metal organic frameworks and polyoxometalats have recently introduced [1-4].
