摘要:
<正>用质量分数分别为0、0.3%、0.6%、0.9%的NaCl营养液对德国鸢尾8#(Iris germanica’ white and blue’)和蓝蝴蝶(I. tectorum)植株进行根际盐胁迫,处理时间为4d和8d。结果表明:两种鸢尾受盐胁迫后,随着NaCl浓度提高和胁迫时间延长,叶片的质膜相对透性增大,而蓝蝴蝶的膜透性增大程度比德国鸢尾更为明显。MDA含量也是蓝蝴蝶高于德国鸢尾8#。说明了在盐胁迫下德国鸢尾8#叶片质膜受损伤的程度较轻。德国鸢尾8#叶内保护酶SOD活性及渗透调节物质脯氨酸和可溶性蛋白含量都显著高于蓝蝴蝶。研究证实了德国鸢尾8#比蓝蝴蝶具有相对较强的抗盐能力,其较小的质膜透性和MDA含量,较高的SOD活性和脯氨酸及可溶性蛋白含量是鸢尾属5个重要的抗盐生理指标。
Abstract:
The catalytic characteristics of PW12 heteropoly-acid supported on several dome, stic activated carbons were investigated for the esterification of acetic acid with terpineol in the liquid-solid system. XRD and NH3-TPD of catalyst were studied in detail. Different activated carbons had remarkably different adsorption strength for PW12. The effects of reaction conditions were studied. The most suitable conditions for the reaction were obtained. The results showed that this catalyst had a higher catalytic activity, which made the produce process of the esterification of acetic acid easy, also it could easily be recovered and could be used repeatedly many times.
