“…Cm(III) (10 À7 mol L À1 initially) was extracted from an aqueous phase (20 mmol L À1 SO 3 -Ph-BTP in 0.7 mol L À1 HNO 3 ) to an organic phase (0.2 mol L À1 TODGA + 5 vol% octanol in TPH). Following phase separation, both phases were investigated by TRLFS and the emission spectra of Cm(III) were compared with those of known homoleptic Cm(III) complexes, [Cm(SO 3 -Ph-BTP) 3 ] 9À in the aqueous phase, 15,33 and [Cm(TODGA) 3 ](NO 3 ) 3 in the organic phase, 44 Fig. 1.…”

“…[25] Within the lanthanide group, the distribution ratios increase with decreasing ionic radius of the lanthanide. [26] Figure 3 shows the comparison of the distribution ratios of Ln(III) and An(III) using TODGA against (SF La/An ≈ 50), but the selectivity for curium over americium (SF Cm/Am ) is significantly higher. [24] The initial concentration of the Ln(III) in the aqueous phase was 10 -5 mol·L -1 of each lanthanide.…”

An americium(III) selective separation procedure was developed based on the co-extraction of trivalent actinides (An(III)) and lanthanides (Ln(III)) by TODGA (N,N,N',N'-tetraoctyldiglycolamide), followed by Am(III) selective stripping using the hydrophilic complexing agent 3',3'',2,5,6,tetrayl]tetrabenzenesulfonic acid). Distribution ratios were found at an acidity of 0.65 mol L -1 nitric acid that allowed for the separation of Am(III) from Cm(III) (D Cm > 1, D Am < 1), giving a separation factor between curium and americium of SF Cm/Am = 3.6 within the stripping step. The formation of the 1:1 complex was suppressed in 0.5 mol L -1 nitric acid but it was significantly present in HClO 4 at pH 3. Conditional stability constants of the complex species were calculated from the TRLFS experiments.

ABSTRACT. We identified and analyzed 5 new-type enterotoxin genes, including SEj, SEl, SEq, SEm, and SEr, to explore the distribution of 5 enterotoxin genes in Staphylococcus aureus of different origins as well as their correlations and differences. We examined the distribution of the S. aureus enterotoxin genes and their pathogenic mechanisms. A total of 660 specimens were collected from January 2011 to December 2014, and 217 strains of S. aureus were isolated. The template DNA of S. aureus was extracted. The Primer6.0 and Oligo7 software were used to design and synthesize polymerase chain reaction primers. Amplification results were analyzed by electrophoresis, and the amplification products were recovered and sequenced. Thirty-six bacterial strains contained the SEj gene (16.6%), including 15, 8, 8, 4, and 1 strains in fresh meat, quickfrozen food, raw milk, human purulent tissue, and living environment, respectively. Thirty-one bacterial strains contained the SEr gene (14.3%), including 16, 9, and 6 strains in fresh meat, quick-frozen food, and raw milk, respectively. Twenty-one bacterial strains contained the enterotoxin SEq gene (9.7%), including 8, 6, 6, and 1 strains in fresh meat, quickfrozen food, raw milk, and human purulent tissue, respectively. No SEm and SEl genes were detected. Different types of foods carry different types of enterotoxins, providing a basis for quick tracing for food poisoning. Three enterotoxin genes, SEj, SEr, and SEq, showed the highest carrier rate in quick-frozen food. It is imperative to improve their detection in quick-frozen food.
