[Inventory of final energy-carbon consumption and its structure in Beijing].

Final energy-carbon consumption by different sectors and fuel types in Beijing from 1995 to 2005 and energy structure were presented according to IPCC reference approach and statistical data. Specific discussion of energy-carbon consumption category of each industry in 2005 was given. From 1995 to 2005, total and per capita final energy-carbon consumption increased respectively by 71.

Treatment of methyl orange by calcined layered double hydroxides in aqueous solution: adsorption property and kinetic studies.

Adsorption of a weak acid dye, methyl orange (MO) by calcined layered double hydroxides (LDO) with Zn/Al molar ratio of 3:1 was investigated. In the light of so called "memory effect," LDO was found to recover their original layered structure in the presence of appropriate anions, after adsorption part of MO(-) and CO(2-)(3) (come from air) intercalated into the interlayer of LDH which had been supported by XRD and ICP. The results of adsorption experiments indicate that the maximum capacity of MO at equilibrium (Q(e)) and percentage of adsorption (eta%) with a fixed adsorbent dose of 0.
