Anaerobic digestion of biomasses originates different products, the most abundant of which are methane and carbon dioxide. During this process, a 60-70% organic matter reduction occurs and the final p...
干废弃啤酒酵母菌对铅离子的吸附及FTIR分析
啤酒酵母菌 生物吸附 铅离子
2009/10/29
以啤酒厂废弃啤酒酵母菌为原料，利用原子吸收光谱(AAS)、扫描电子显微镜/X射线能谱仪(SEM/EDS)、傅里叶红外光谱(FTIR)等手段，研究其对Pb2+的生物吸附规律，并对吸附机理进行了探讨。结果发现实验条件下，啤酒酵母菌对Pb2+的吸附是一个快速过程，实验进行30 min时酵母菌的吸附量为47.6 mg·g-1,吸附效率已达到91.6％，90 min时基本达到吸附平衡，此时酵母菌实验吸附量为...
应用TGA-FTIR研究不同来源污泥的燃烧和热解特性
热解 燃烧 热重-红外分析
2008/5/30
在空气气氛下，利用热重分析方法研究了三种不同来源的污泥燃烧特性。探讨水处理工艺和污泥处理工艺对污泥中有机物的分布影响和燃烧特性影响。研究发现，污水厌氧工艺和污泥厌氧工艺均导致结构复杂、燃烧温度高的有机物生成。在氮气气氛下利用热重红外联用技术，对比研究了同种污泥的热解和燃烧特性，污泥热解主要发生有机物裂解成小分子和小分子的挥发，氧气的存在加速了污泥的裂解。污泥热解温度200℃～500℃，主要气体H2...
Gas Pollutant Emissions from Smoldering Incense Using FTIR
Incense Smoldering Emission rate and factors
2016/3/30
This study characterized the effects of smoldering incenses and combustion conditions on
gaseous pollutant yields. Incense comes in three types: non-smoke (A), reduced-smoke (B) and
traditional-smok...
