Aiming at above problem, this paper put forward the strategy of separation as follows. Firstly, in view of great amount of coloring matter in solution, the quality of product is declined. So we decolor the solution by acticarbon, which makes 80% coloring matter be removed, but the loss of nucleotides is only about 2%. Secondly, on the basis of physical and chemical properties of four nucleotides, we first synthesized a kind of cation exchange resin by ourselves which is used to separate four matters preliminarily.
针对以上问题,本文提出了如下的分离策略:首先,由于酶解液中色素含量较多,使经树脂分离所得UMP和GMP中色素残留较多,最终导致成品质量的下降,所以我们用活性炭对酶解液进行脱色处理,使溶液中80%以上的色素被吸附除去,而核苷酸的吸附损失仅为2%左右。

Regardless to the research development or industrial application, nano metal powders are extensively discussed. Within these powders, the flammable and explosible nano aluminum, titanium and iron powders produce a great amount production and apply widely. Meanwhile, the surface/volume ratio of powders is increased significantly under nano scale, in which to enhance the ignition opportunity. Thus, the dust explosion hazard risk of nano powders could remarkable rise. In addition, the comparison of explosion phenomenon, test methods and quantification parameters between nano and micro scale is necessary to deeply investigate further. So that this project operates the explosion characteristic experiments to measure and determine such the maximum explosion pressure, minimum explosion concentration and explosion characteristic Kst value on above mentioned three nano metal powders. Expectantly, to provide the appropriate recommendations of safety prevention for nano dust explosion based on the experimental results.
奈米金属粉末无论是研究发展或是工业界应用,目前皆是广泛讨论研究之材料,其中,奈米铝粉、奈米钛粉以及奈米铁粉等可燃、爆性粉末,均有高额产量及大量应用领域,与此同时,在粉末粒径进入奈米尺度的情况下,粉尘比表面积大幅提升,增加此三种粉尘可被点燃的机会,因此,潜在的粉尘爆炸危害风险将广幅增加,另外,微米尺度粉尘爆炸的现象、测试方法以及量化参数是否具有相同的实验尺度基点,也需要深入探讨,故本次计画针对上述三种奈米金属粉末,进行三种不同粒径的爆炸特性参数实验,如最大爆炸压力、最低爆炸浓度以及爆炸特性参数Kst值之量测与计算,期能量化其粉尘爆炸特性,并据此提出适当的安全防护建议。
