Abstract: Through mild heat treatment of soybeans at an elevated temperature, soybeans show an ordered porous structure, then the static adsorption method and FTIR analysis are used to study the adsorption of neutral red dyes and heavy metal ions. The research contents mainly include: the influence of initial concentration and the initial pH value on the adsorption, and the adsorption kinetic process. It is observed that in the range of acid to weak alkali, the removal rate to neutral red dye is better than other pH value range, and best when the pH is equal to 7. The initial concentration on the adsorption is also an important factor affecting the removal rate and adsorption capacity. At the same time, the removal rate of the adsorbent and the adsorbate in the first 20 minutes of contact is above 80% during the adsorption process. By fitting, the adsorption behavior is more consistent with the quasi-second-order kinetic model. Porous soybean is not only friendly to human beings, but also demonstrates the advantages of high adsorption capacity and low cost. Therefore, it will be a promising environmental cleaning material .
