中子辐射俘获反应在反应堆运行、核装置设计及核天体物理研究中起重要的作用.4πBaF_(2)探测装置有着高时间分辨能力、低中子灵敏度、高探测效率等优点,适合开展中子辐射俘获反应截面数据的测量.中国原子能科学研究院核数据重点实验室建立了伽马全吸收装置(Gamma total absorption facility,GTAF),该装置用28块六棱BaF_(2)晶体和12块五棱BaF_(2)晶体构成了外径25 cm,内径10 cm的球壳,覆盖了95.2%的立体角.利用GTAF在中国散裂中子源Back-n束线上,测量了197Au(n,γ)的反应截面数据.测量数据通过能量筛选、PSD方法、晶体多重性筛选进行了初步本底扣除,随后结合对^(nat)C及空样品的测量数据对本底进行了分析及扣除,获得了197Au俘获反应的产额,利用SAMMY程序拟合得到了^(197)Au在1—100 e V的共振能量、中子共振宽度和伽马共振宽度参数.实验测量结果与ENDF/B-VIII.0数据库符合良好,其共振参数存在一定差异,分析原因可能与GTAF能量分辨率、Back-n的中子能谱测量精度、以及实验本底扣除方法相关,这也是下一步工作的重点.

采用紫外分光光度法研究了四环素类药物(Tetracyclines,TCs)在不同pH条件下分子结构的变化,用分子荧光法、高效液相色谱法(HPLC)探讨了TCs在蛋白质基体中的存在形态,同时讨论了蛋白质对提取水产品样品中TCs残留的影响。结果表明,TCs与蛋白质有较强结合作用;适当浓度的(NH4)2SO4与HPLC流动相(甲醇-乙腈-0.02 mol/L草酸混合溶液,20∶20∶60,V/V)混合提取液可引起蛋白质缓慢且完全变性,导致蛋白质与TCs络合物离解,释放结合的药物,从而提高蛋白质样品中TCs残留提取的效率。本方法用于测定水产品中的土霉素、四环素、金霉素和强力霉素,测定回收率为88.2%～95.4%,RSD为1.3%～4.9%,检出限为14.8～39.2 ng/g。本方法操作步骤简单、快速、可靠。

利用荧光猝灭法与GC-MS研究了邻苯二甲酸酯类(PAEs)在以蛋白质为主要基质的水产品中的存在状态,探讨了蛋白质对PAEs萃取率的影响。结果表明,PAEs可通过氢键和范德华力与蛋白质牢固结合;体积分数为80%的异丙醇水溶液可引起蛋白质缓慢变性、使结合的PAEs充分离解,通过异丙醇-无机盐-水双水相体系实现PAEs的高效萃取。由于80%的异丙醇水溶液极性较强,与PAEs共同进入双水相上相的脂溶性杂质较少,萃取液净化步骤大大简化。在双水相上相中加入无水MgSO4、N-丙基乙二胺(PSA)去除水分与杂质后直接进样进行GC-MS检测。该方法用于水产品中五种PAEs的测定,回收率为81.9%～92.7%,相对标准偏差为1.2%～4.8%。
