聚丙烯酰胺生物降解研究进展

, 2005
聚丙烯酰胺(PAM)是丙烯酰胺均聚物和各种共聚物的统称,作为一种高技术含量、高附加值的重要化工产品,已广泛应用到工农业生产的各个领域并渗透到人们的日常生活中.过去通常认为聚丙烯酰胺是非常稳定的高分子聚合物,事实上,在自然条件下,聚丙烯酰胺会发生缓慢的物理降解(热、剪切)、化学降解(水解、氧化以及催化氧化)和生物降解,最终生成各种低聚物以及具有神经毒性的剧毒丙烯酰胺单体,对人体造成了极大的间接或直接危害.因此,进行聚丙烯酰胺的降解研究很有意义,而聚丙烯酰胺的生物降解研究领域几乎为空白 ...

一种采用聚乙二醇/碱法降解溴系阻燃剂的方法

, 2013
本发明涉及降解溴系阻燃剂的方法，具体的说是一种采用聚乙二醇/碱法降解溴系阻燃剂的方法。在温和条件同时助剂的存在下，以聚乙二醇/碱作为亲核试剂与溴系阻燃剂反应生成芳基醚聚乙二醇和芳基醚醇，而后再加热使芳基醚聚乙二醇生成芳基醚醇，进而达到降解溴系阻燃剂的目的，具体如下式所示。本发明效率高、反应条件温和，反应产物易于处理，操作易于控制 ...

滇池沉积物菌群对微囊藻毒素的厌氧生物降解

, 2009
好氧微生物降解已经被证明是微囊藻毒素(MC)自然转化的主要途径,但是厌氧降解的作用尚不明确.为了揭示这一降解过程,研究了滇池沉积物中混合菌群在厌氧条件下对MCLR的降解能力,并考察了环境因素和外加营养源对该过程的影响.结果表明,厌氧条件下MCLR在2 d内从5 mg/L迅速降解到检测限以下,说明该菌群在厌氧条件下对MCLR具有较强的降解能力,并且可以利用MCLR作为唯一氮源.在实验温度范围内,MCLR的降解速率随着温度的升高而增大.酸性条件下MCLR的厌氧降解缓慢(pH=5.0)甚至停止(pH=3.0)
