“…SEPs had a high adsorptive capacity for moisture due to its structural channels. [14] The effect of SEPs on the moisture adsorption of the composites was revealed in Fig. 5, which showed the relation of storage time and water contents of GPS and the composites at 100%.…”

Two sepiolites (SEPs) were respectively used as the fillers in glycerol plasticized-cassava starch (GPS) matrix by the casting process. Scanning electron microscopy proved that SEPs were dispersed well in the GPS matrix. Fourier transform infrared spectroscopy indicated that silanol groups at the external surface of SEPs could form the interaction with C-O-H and C-O-C groups in starch molecules. The introduction of SEPs improved the tensile strength, thermal stability, the pasting viscosity and restrained water vapor permeability, but reduced the elongation at break of the composites. SEP-fiber imparted the composites better properties than SEP-velvet, except for the resistance of moisture adsorption. SEP-velvet could decrease the water contents at the equilibrium of the composites.

“…Thus, the available heavy metals in T6 were less than those in T3. However, the sepiolite powder was rich in Mg 2þ and Ca 2þ [48] whose concentrations in soil had a positive relation to the accumulation of heavy metal in plants. Therefore, the concentrations of Cd and Cu in R. chuanxiong in T3 were lower than those in T6.…”

An improved method was applied for remediating cadmium and copper co-contaminated soil and reducing the metal concentration in Rhizoma chuanxiong. Pot experiments were conducted with six amendments (composed with bentonite, phosphate, humic acid, biochar, sepiolite powder, etc.). The results showed that soil pH, biological activities (soil enzymatic activities and microbial counts) and R. chuanxiong biomass were greatly improved with the addition of amendments in all treatments, especially in T3 and T6. Also, amendments effectively decreased the concentration of malondialdehyde and H2O2 in R. chuanxiong. In the T3 treatment, the bio-available Cd and Cu in soil were significantly decreased by 0.53 and 0.41 mg kg−1, respectively. Meanwhile, the amendment in T3 reduced Cd and Cu accumulation in R. chuanxiong about 45.83 and 39.37%, respectively, compared to T0. Moreover, the Fourier transform infrared spectroscopy spectra showed the surface functional groups of every amendment. To conclude, this study offers an effective and environmental method to reduce metal accumulation in R. chuanxiong on heavy metal co-contaminated soil.
