In order to decrease the content of heavy metals in the crops soils, a novel method based on using an aqueous solution bearing cysteamine as the key ingredient was studied to extract the polluted heavy metals including Cd, Cu, Zn, Ni and Pb. By using the single-factor method, remediation-related technical index were screened and they are, respectively, applied to the solid material whereby the heavy metals are released and extracted from the solid material. The biomass solution residues remaining in the solid material after the heavy metal extraction procedure is rapidly biodegradable, so that no objectionable traces remain in the solid materials or soils. 展开更多

In this study, well-dispersed gold nanoparticles were prepared by using intra-molecular reduction of sodium gold sulfite, without using additional reductants and chloride free. The technical parameters including transformation temperature, pH, and concentration were optimized by the single-factor method as 90 C, pH 1, and 0.01 mmol/L [Na3Au(SO3)2], respectively. The resultant colloidal transmission electron microscopy images (TEM) and UV-vis absorption spectrophotometer spectra were acquired to check their properties, and the results show this kind of colloidal gold is controlled to 6 nm in sizes and has good stability in solution. 展开更多
