Oil adsorption materials with hierarchical pores were successfully synthesized using agriculture solid wastes kenaf core (KC) as precursors. Typically, the base materials were firstly pretreated by high shear dispersion and then freeze-dried and subsequently modified by MTMS. The as-prepared samples were further characterized by a series of techniques including SEM, FTIR, XRD and BET etc. to determine the morphology structure, physicochemical properties and thermal stability. The obtained materials possessed promising super-hydrophilic feature with a density of 0.019g/cm3 which enabled it float on the water surface and was favorable for the rapid adsorption of oil and organic solvent. Additionally, the influence of kenaf core sizes, basicity and solid concentration in suspension were deeply investigated. Herein, the experimental results indicated that the optimal adsorption conditions for oil were as following: particle sizes of kenaf core (20-40mesh), 40g/L NaOH and 10g/L KC. Interestingly, the materials could adsorb as many as 20-45 times of its own mass for DMSO, CCl4, diesel and crude oil etc within 30s. This might shed light on the development of novel adsorbent.
