Hot Test

The crown ether strontium extraction(CESE) process for partitioning strontium from HLLW was studied. A hot test was carried out in a counter current mode with genuine HLLW by using a miniature centrifugal contactor set. 0.1 mol/L DCH18C6 in 1-octanol was used as extractant. The feed solution was the HLLW raffinate of TRPO process after removing TRU elements. Acidity of the feed was 1.45 mol/L HNO

Tobacco stem and tobacco dust are the major raw materials in the reconstituted tobacco production. The extraction of the components from these materials is one of the most important procedures in making the reconstituted tobacco sheet. In this paper, we reported an approach of three-stage counter current extraction to transfer the components from tobacco stem and tobacco dust. The results showed that the extraction ratios for tobacco stem and tobacco dust were 40.2% and 54.2%, respectively. The testing results on the extracted tobacco stem and tobacco dust showed that the overall extraction ratios of water soluble sugars, total alkaloid, and chloride in tobacco dust were 89.3%, 90.5% and 100%, respectively; and the overall extraction ratios of water soluble sugars, total alkaloid and chloride in tobacco stem were 59.3%, 60.3% and 76.2%, respectively; The contents of total nitrogen in tobacco dust and tobacco stem were basically no change after each extraction. Lower extraction yield and higher extraction ration were obtain by three stages extract than those by single stage extract.

ABSTRACTCounter current Immunoelectrophoresis was used to detect porcine cysticcrcosis and water soluble extracts of scolex and of scolex with cyst wall were used as antigens. Serum samples from 40 pigs infected with Cysticercus cellulosae, five infected with C. tenuicollis and five with hydatid cysts, and 15 healthy pigs were tested. A sharp and thick concave precipitin band was observed at the point of interaction of antigen and antibody within 90min in 39 sera from infected pigs (97–5%). The precipitin reaction was better in barbitone buffer of pH 8–6 with the well distance at 6 mm. No false or cross reaction were found and the test was rapid and sensitive.

Scalable Production

We reported the scalable production of iron oxide nanowhiskers from 250 mL laboratory scale to 10 L reactor reaction. During the scale-up process, the reaction time was found to be a critical parameter to adjust for the production of iron oxide nanowhiskers with similar quality to that of the laboratory scale. Based on transmission electron microscopy and magnetometry analysis, the size, size distribution, and magnetic properties of the large scale products were comparable to those produced on laboratory scale. Subsequently, these nanowhiskers were transferred from organic solvents to aqueous solution using a 38-liter stainless steel tank. These water soluble nanowhiskers were well dispersed in water and the surface chemistry was confirmed by Fourier transform infrared spectroscopy.
