医疗废物制备木酢液及其成分分析

THE PREPARATION AND COMPONENT ANALYSIS OF WOOD VINEGAR BASED ON MEDICAL WASTE

为了解以医疗废物为原料的木酢液制备特性和木酢液的成分,采用磁化热解装置进行调制试验,收集了热解冷凝液,并采用GC-MS对冷凝液的成分进行了分析。检测出有机酸、酚、醛、酮、酯等38种有机成分,并采用面积归一化法对主要成分进行定量分析。结果表明,医疗废物磁化热解冷凝液中的成分种类与木酢液十分接近,特别是乙酸(18.48%)与苯酚(5.15%)的含量较高,证明了依靠磁化空气热解医疗废物制备木酢液的可行性。而两者之间存在的成分差异对其功用的影响则有待进一步探究。

To understand the preparation characteristics and component of the wood vinegar based on medical waste as the raw material,the magnetic pyrolysis experiment have been modulated and the condensed liquid has been collected to do component analysis by GC-MS. Thirty-eight kinds of organic ingredients have been detected out,including organic acids,phenols,aldehydes,ketones and esters. Using the area normalization method for quantitative analysis of the main components,the results showed that the component of condensed liquid from magnetized pyrolysis of medical waste was very close with the wood vinegar,especially the high content of acetic acid( 18. 48%) and phenol( 5. 15%),which proved that it was possible to prepare wood vinegar from medical waste by magnetized pyrolysis. However,the influence on the function caused by the differences in component between the two kinds of liquids needs further exploration.
