This study investigated the effect of leachate DOM on the adsorption of Cu, Cd, Pb and Zn in the typical cinnamon soil in Northern China. The adsorption experiments were conducted under the conditions of isotherm at 15, 25 35°C and at various acidities (pH=5-9). The results revealed that the process of soil adsorb these metals is accord with the adsorption isotherm formula of S=KCN and S=SmC/(C+1/K)...
Zinc sulfide nanoparticles were prepared by hydrothermal method and characterized by TEM, FT-IR and BET surface area. The titration results show that the surface of ZnS nanoparticles possessed an obvious acid-base property. With increasing the amount of ZnS nanoparticles in the suspension, the pH buffer capacity of solution increased dramatically. There is a proportional relationship between the amount...
A highly sensitive and selective spectrophotometric method is proposed for the determination of trace lead in food. The method is based on the reaction of lead(II) with a new analytical reagent trihydroxyphenylfluorone (TH-PF). TH-PF reacts with lead(II) and form a stable 1 : 2 complex at pH 10.40. Its apparent molar absorption coefficient and Sandell's sensitivity at 580 nm are 4.56 times 104 L/mol/cm...
