The main steps include as follows: CO2 is led into the mother liquor of sodium meta-aluminate to carry out carbon content decomposing; the primary separation between the aluminum and the gallium is realized by primary carbonatation to filter out sodium hydroxide; secondary carbonatation is carried out on the filtrate to obtain the deposit of the complex salt of gallium and aluminum; a sodium carbonate crystal is obtained after the filtered filtrate is condensed and vaporized; the deposit of the complex salt of gallium and aluminum is dissolved in the mother liquor of sodium meta-aluminate; the processes are repeated until the proportion of gallium and aluminum in the complex salt of gallium and aluminum is larger than 1/340; then the complex salt of gallium and aluminum is added into the NaOH liquor and electrolyzed, thus obtaining the metal gallium with a purity larger than 99.9 percent which reaches the level of 3; simultaneously, the byproducts of the aluminum hydroxide and the sodium carbonate during the process of carbonatation by steps are obtained.
主要步骤包括:向铝酸钠母液中通入CO 2 进行碳分分解,一次碳酸化实现铝镓的初次分离;过滤出氢氧化钠,滤液进行二次碳酸化获得镓铝复盐沉淀,过滤后滤液经浓缩蒸发获得碳酸钠晶体,铝镓复盐沉淀溶解在偏铝酸钠母液中,重复上述过程直至铝镓复盐中的镓铝比例大于1/340,将其加入到NaOH溶液中,电解可获得纯度>99.9%的金属镓,达到3N级水平同时在分步碳酸化的过程中获得氢氧化铝和碳酸钠副产品。

Persculptus to Parakidograptus acuminatus Zones, could be recognized during the interval. In addition, the abundance changes of the radiolaria at the Goujiaya and Datangkou sections were coincided with the sea-level changes, and correlatable with the synchorous 5 fluctuations of the sea-level in North America and Africa. So above-mentioned 5 cycles could represent the eustasies during the latest Ordovician to the earliest Silurian.
在这2个剖面上,放射虫丰度变化也表现出相似的规律,与笔石和腕足类的形态、分异度和丰度变化所反应的海平面升降大体一致,和北美、非洲同期海平面的5次波动可以对比,据此指出,以上5次海平面旋回代表了晚奥陶世晚期至志留纪初期全球性海平面变化。

Methods The SpaA was purified by electroelution from NaOH-extracted antigen of Erysipelothrix rhusiopathiae strain C43311. The rSpaA-N was expressed in E. coli BL21 as a soluble protein by IPTG inducing,and purified with GST affinity chromatography. Mice of each group were subcutaneously immunized three times with 50μg or 100 μg of native SpaA, rSpaA-N or NaOH-extracted antigen with in complete or incomplete Freund adjuvant at 2-week intervals.
将猪丹毒丝菌C43311株SpaA-N以可溶形式表达在大肠杆菌BL21中,用GST Bind Resin纯化试剂盒纯化rSpaA-N,采用电洗脱法从猪丹毒丝菌C43311株NaOH提取抗原中纯化天然SpaA,将rSpaA-N、天然SpaA和NaOH提取抗原制成亚单位疫苗,同时设GST及生理盐水对照组,间隔2周分3次皮下免疫小鼠,第3次免疫后2周用100LD50猪丹毒丝菌C43065株进行腹腔攻毒,采用间接ELISA方法检测免疫组小鼠血清的抗体动态变化。
