130 wet deposition events were observed at the summit of Mt. Tai (East China, 1534 a.s.l) in China during Jan. 2005 to Dec. 2008. Zn, Al, Mn, Fe, Pb, Cu, Ni, Cr, As, and Cd were determined by ICP-MS to evaluate the characteristics of heavy metals in wet deposition at Mt. Tai region. The concentrations of these metals are generally higher at Mt. Tai than the concentrations observed at other monitoring...
A series of catalysts with various Co/Ni and M2+/M3+ mole ratios were prepared by decomposition of Co/Ni/Al hydrotalcite-like compounds(HTLcs) precursors at 350??C and used for hydrolysis of carbonyl sulfide(COS). The effect on the catalytic performance was investigated at 50??C and GHSV of 1000~3000 h-1 with relative humidity of 2.40%. The catalyst with Co/Ni at 0.25~0.5 and M2+/M3+ at 2~3 had the...
We investigate both end-contact and side-contact structures between Al, Pd, Sc and carbon nanotube (CNT) in this paper. The different structures show the different chemical bonds and charge transfer at the metal-CNT contact interfaces. A novel method based on dipole effect is proposed to calculate the Schottky barrier height (SBH). Different SBHs for the contacts are due to different electro-negativity...
An investigation was conducted to study the effect of humic substance (HS) on the phosphorus (P) solubility in acidic soil. The soil (2.5 g), HS (0, 0.5, and 2.5 g), and P as monocalcium phosphate (0.31 and 1.25 g P kg −1 soil) were mixed with 50 mL distilled water and two different sequences of adding HS and P were used. The results indicated that the P concentration in water and 0.01 mol...
