Effects of Straw, Phenol and Organic Acids on Soil Carbon in Different Sized Particles under Different Nitrogen Levels 不同氮水平下秸秆和酚类、有机酸对土壤碳含量的影响
The results showed that the major odor pollutants are hydrogen sulfide, organic sulfide, phenol, organic amine and organic acids. 结果表明:主要恶臭污染物为硫化氢、有机硫化物、苯酚类、有机胺及有机酸等;
Separation of phenol acids with paper chromatography 胶束纸色谱法分离酚酸
The main intermediates of phenol degradation were benzoquinone and organic acids such as oxalic acid and maleic acid and the final product was carbon dioxide, therefore the technique could be used as a waste minimization process for recycling the treated water. 苯酚降解的主要产物为苯醌、丁烯二酸和草酸,最终产物为二氧化碳,因此该工艺可用于有机物污染最小化处理和处理水的回用。
Separation of phenol acids with paper chromatography Study of the Fabrication Process of Lead Styphnate by FT IR Method 胶束纸色谱法分离酚酸斯蒂酚酸铅制备工艺的红外光谱研究
Each ton production of sebacic acid will produce 30 tons effluent in present process. What the wastewater contain are sodium sulphate, sebacic acid, phenol and other fatty acids. 目前的生产工艺中,每生产1吨癸二酸,需排放约30吨废水,废水中含有的主要杂质为硫酸钠、癸二酸、苯酚以及其他一些脂肪酸。
Phenol is great harm to humans and other creatures, and is recognized as a carcinogen; phenolic acids are derived from refined chemical products of phenolic compounds. 酚对人和其他生物的危害极大,是公认的致癌物质。
