Compared with the conventionalemulsion polymerization system in the presence of sodium dodecyl benzene sulfonate, the latices prepared by emulsifier-free emulsion polymerization have much more narrow distribution of latex particle sizes (0.2um in diameter), better resistance to electrolytes, pH, freeze-thaw, and better mechanical stability. Not only the tensile strength of the copolymers prepared by this method is obviously increased, but also the water resistance and adhesion capacity are significantly enhanced. On the other hand, the TG results indicate the copolymer has lower thermal stability than conventional copolymer.

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 acute toxicity experiments, the 96h-LC50 were 1.0×105 cells·mL-1 for the intact algal solution and 8.0×104 cells·mL-1 for the lysate. In a 7 day subacute experiment on the larvae, higher concentrations of algal solution inhibited S. macrocephalus larvae. The toxicity of the algal solution was higher than that of the lysate at the same concentration.

The diagrams indicate that microemulsions can only be formed with a certain Combination of SDS and n-bulanol. A stretch of microemulsion domain changing continuously from direct micelles to bicontinuous structures and to reverse micelles exists when the surfactant to cosurfactant ratio is comparatively low, while the direct micelle area is separated from the reverse micelle area by a mesomorphic medium when the surfactant to cosurfactant ratio is comparatively high.
