A novel method for determination of benzoyl peroxide with spectrophotometry was developed. Inclusion ratio of β cyclodextrin to dibenzoy peroxide and benzoic acid is obtained with spectrophotometry.The mechanism of the inclusion was studied,too. The results showed that β-CD react with dibenzoyl peroxide to form a 1:1 or 2:1 host-guest complex, with the apparent formation constants of 5.0× 10~2and 2.5× 10~4 , respectively.β-CD reacts with benzoic acid to form a 1:1 host-guest complex with the apparent formation constant of 6.9 × 10~2 after the dibenzoyl peroxide was reduced by hydroxyl ammonium chloride.

Results show that, following the leaching time extending, the leaching concentrations of heavy metals and lixiviate toxicity of heavy metals increase in the fly ash. When the ratio of liquid and solid add, the leaching concentrations of heavy metals obviously become big, and the Cd's leaching concentration is the biggest, when the ratio of liquid and solid is 90, the Cd's leaching ratio exceed the percent of 70. At the time pH is about 7, the leaching concentrations of heavy metals are the lowest. When the grain size is the bigger or little, the leaching concentrations of heavy metals are lower, however when the grain size is 250-900 μm, the concentrations are higher. After fly ash melt in the high temperature, the lixiviate toxicity of heavy metals greatly reduce, which explains that the effect of melting on heavy metals' stabilization is very good.

结果表明，随着浸出时间的增加，飞灰绝大部分重金属的浸出浓度增高，浸出毒性增强；液固比增加，大部分重金属的浸出率大大提高，其中重金属Cd的浸出率最大，在液固比为90时，飞灰中的Cd的浸出率达到70%以上；pH为中性左右的时候，医疗垃圾飞灰中的大部分重金属的浸出液浓度最低；颗粒尺寸在较大或者较小时，医疗垃圾飞灰中的大部分重金属浸出浓度较小，大部分重金属在颗粒尺寸250～900 μm时，重金属的浸出浓度较高；飞灰高温熔融后，重金属的浸出毒性大大降低，说明熔融对重金属有很好的固化效果。

In the paper, the multidentate carboxylic acid ligands were used to combine with Cd, resulting in the three dimensional MOCPs single crystals—C12H16CdN2O8, with a low temperature hydrothermal synthesis method. The sample was characterized with IR spectra to affirm the organic groups in the frameworks, single-crystal X-ray diffraction to determine the crystal structure and composition of the frameworks, N2 adsorption isotherms at low temperature to measure the specific surface area and pore size distribution, and with TGA/DGA analysis to scale the thermal stability. Furthermore, the dissolution property and the photocatalytic activity of MOCPs under the ultraviolet ray condition were explored.
