大气汞的形态转化及其影响因素是汞研究领域的热点之一,目前有关低对流层大气光化学过程对大气活性汞的影响研究仍十分有限.本研究将双级阳离子交换膜(CEM)与Tekran 2537汞监测仪相结合,搭建了双通道大气汞监测系统,并对沿海城市厦门2023年5—9月的大气气态汞浓度开展了观测.结果表明,观测期间厦门地区气态元素汞(GEM)和气态活性汞(RGM)平均浓度分别为(2.10±0.74)ng·m^(-3)和(218±131)pg·m^(-3).RGM月均浓度表现为7月>8月>6月>9月>5月,其主要原因是夏季较高的温度和太阳辐射促进了GEM向RGM的转化,同时高温不利于RGM由气相向颗粒相的分配.厦门7—8月GEM浓度相对较高,这可能与台风的频繁影响有关.在日变化特征上,厦门GEM和RGM均在清晨达到最高值,在傍晚下降到最低值,表现出边界层厚度变化驱动的特征.研究期间经常监测到极高的RGM浓度,其中一些持续了数天.F0AM模型模拟结果显示,在RGM高浓度事件过程中,RGM受到来自本地或外来光化学氧化的影响相比大气传输和人为源排放更为重要.

在环氧乙烷法合成牛磺酸的工艺路线中,杂质亚氨基二乙磺酸单钠(SA)会不可避免地进入结晶工序,杂质的存在会对牛磺酸产品的性质产生显著影响。本工作考察了SA浓度和降温速率对牛磺酸晶体形貌的影响,采用分子动力学模拟方法分析了SA在牛磺酸晶面上的附着情况以及SA改变牛磺酸晶体形貌的原因。结果表明,牛磺酸长径比随着SA浓度增加和降温速率加快而增大;降温速率为30 K/h时,添加浓度为0.04 mol/kg的SA会使牛磺酸晶体的平均长径比增加1倍以上;SA浓度为0.02mol/kg时,随着结晶冷却速率从6 K/h升至36 K/h,晶体的平均长径比增大约3.8倍。结晶过程的降温速率应控制在12 K/h以下,以获得平均长径比小于3的牛磺酸晶体产品。模拟结果表明,基于修正的附着能模型模拟得到的晶习和实验晶习一致;■晶面的面积占比缩小,(102)和■晶面的面积占比扩大,这是SA水溶液中牛磺酸晶体生长成针状形貌的根本原因。本研究有助于理解SA改变牛磺酸晶习的作用机理和指导牛磺酸结晶工艺的优化。
