摘要

针对H2O2预氧化对生化黄腐酸（BFA）钙盐复合物的融雪化冰性能影响及其机理进行了研究。结果表明，在H2O2与BFA质量比为1.5、pH 7.5、35℃的最佳预降解条件下反应120 min，可使BFA钙盐复合物的冰点降低27%。紫外光谱、红外光谱及凝胶色谱分析结果表明，BFA经H2O2氧化降解后，一些复杂的芳香族有机物发生降解甚至开环、不饱和脂肪烃被氧化，产生了大量小分子羧酸、醇、酚及烯烃等有机物。它们在Ca2+的络合作用下形成了小分子聚合物或共聚物，在融雪化冰中起主要作用。增加BFA结构中的-COOH、-OH和ph-OH等亲水性基团含量是提高BFA钙盐复合融雪剂性能的关键。

Abstract

Biochemical fulvic (BFA) was degraded by hydrogen peroxide (H2O2) before it compounded with calcium salts to be the snow-melting agent. The effect of H2O2 concentration

temperature and pH on the freezing point of BFA compound was studied

and its snow-melting mechanism was analyzed by UV

FTIR and GPC. The optimal conditions in degradation were as follows:ratio of H2O2 to BFA was 1.5 ml/g

temperature 35℃ and pH 7.5

at which BFA had been degraded for 120 min and the freezing point of BFA compound reduced by about 27%. The results showed that H2O2 resulted in the ring opening of some complex aromatic hydrocarbon and oxidation of some unsaturated aliphatic hydrocarbons to produce lots of small-molecular carboxylic acid

alcohol

phenol and alkene arose

which formed some copolymer under Ca2+ complexation. They played the dominant role in ice or snow melting. The experiment results indicated that it was key in improving the property of BFA snow-melting agent and increasing the hydrophilic functional groups of carboxy (-COOH)

hydroxyl (-OH) and phenolic hydroxyl (ph-OH) in BFA.
