The rude antimony trioxide was produced in treatment of copper and lead anode mud and its main components are antimony trioxide, antimony arsenate and lead antimonate. Using the rude antimony trioxide as the additive of cobalt removal can not only decrease operation cost of purification but also find out a new way for utilization of the rude antimony trioxide. The effects of temperature, dosage of zinc dust, the rude antimony trioxide, copper ion and solution pH on removal of cobalt were studied. And experimental data using the rude Sb 2O 3 as additive were compared with those using Sb 2O 3. The results indicate that using rude Sb 2O 3 as additive, cobalt concentration in solution could be decreased from 24 mg/L to below 1 mg/L under about the same conditions as using Sb 2O 3.展开更多

目的:对比研究经胃管和鼻空肠管不同途径给予大黄治疗急性重症急性胰腺炎的治疗效果.方法:SAP患者43例随机分为A组(n=20)和B组(b=23).在综合治疗基础上A组给予胃管注入大黄,B组给予鼻空肠管注入大黄,观察患者住院7、14 d时APACHE-Ⅱ评分...目的:对比研究经胃管和鼻空肠管不同途径给予大黄治疗急性重症急性胰腺炎的治疗效果.方法:SAP患者43例随机分为A组(n=20)和B组(b=23).在综合治疗基础上A组给予胃管注入大黄,B组给予鼻空肠管注入大黄,观察患者住院7、14 d时APACHE-Ⅱ评分,Balthazar CT积分以及CRP及血淀粉酶,肠道功能恢复时间.结果:治疗7 d时B组APACHE-Ⅱ评分较A组有明显降低(3.76±2.82 vs 4.58±2.07,P<0.05),Balthazar CT积分无明显差别(P>0.05):治疗14 d时A组与B组APACHE-Ⅱ评分、Balthazar CT积分均无明显差别(P>0.05);B组CRP及肠功能恢复时间较A组有明显缩短(8.3±1.7 vs 9.1±3.6,P<0.05:6.2±2.9 vs 8.5±2.3.P<0.01).结论:鼻空肠管途径应用大黄能更有效的地控制急性重症胰腺炎的全身炎症反应,缩短病程.展开更多
