Nano-Mg(OH)2, with low biological toxicity, is an ideal nano-carrier for insecticidal protein to improve the bioactivity. In this work, the adsorption features of insecticidal protein by nano-Mg(OH)2 have been studied. The adsorption capacity could achieve as high as 136 mg/g, and the adsorption isotherm had been fitted with Freundlich model. Moreover, the adsorption kinetics followed pseudo-first or -second order rate model, and the adsorption was spontaneous and exothermic process. However, the high temperatures are not...
