Decomposition Characteristics of Hydrogen Peroxide in Sodium Hydroxide Solution

Advanced materials research (2012)

Tian Xiang Guo Yi Zhao Shuang Chen Song Tao Liu

In order to spread more applications, decomposition characteristics of hydrogen peroxide (H2O2) in sodium hydroxide (NaOH) solution were investigated in this paper. Research results indicate that the attack of charged particles such as OH- and HO2- leads to H2O2 decomposition. HO2¬- is vital reactive intermediate, which was mainly from neutral reaction of H2O2 with NaOH. The decomposition is considered as pseudo-two-order kinetics, and the reaction rate constant depended on decomposition temperature and solution pH. The apparent average activation energy is 51.92 kJ•mol-1 when the initial NaOH concentration is 1mol•L-1 and solution pH is 10.5.

An Improved Allocation Method with Environmental Constraints of Regional SO<sub>2</sub> Emission Right

Advanced materials research (2012)

Tian Xiang Guo Yi Zhao Qing Yang Hai Bo Feng De Gui Du

An improved allocation method was proposed to determinate SO2 emission control quantum for certain control area, which was achieved by least square optimization with environmental constraints. In order to avoid local air pollution happening, the concept of potential pollution distribution factor was introduced to determine SO2 actual environmental capacity. In the method, more SO2 emission right and emission trading chances among sub control areas were offered. The case analysis indicated the method was more suitable for emission trading compared with equal-right function method.
