Electrochemical conversion of hypertoxic trivalent arsenic to value-added metallic arsenic can not only contribute to pollution abatement,but also resources reutilization,therefore being widely *** reduction of trivalent arsenic as a promising way is widely ***,the high efficiency conversion is retarded by the sluggish reduction kinetics of AsO33−and fierce evolution of side products of both H_(2)and toxic AsH_(3).Herein,by using the sodium citrate as the additive,the current efficiency for metal arsenic production is increased greatly from 60%to 91%,with the accompanied evolution of hypertoxic AsH_(3)being restrained from 0.15 Nm^(3)/t_(As)to 0.022 Nm^(3)/t_(As),promising a high-efficiency and green *** electrochemical tests and electrode surface characterizations aswell as DFT calculations indicate that the added sodium citrate promotes both the diffusion of reactive AsO_(3)^(3−)towards the cathode and its subsequent adsorption on the Ti cathode,contributing to smoother reduction for generating metal arsenic,with the evolution of toxic AsH_(3)being hindered at the same *** results can provide new insights for the highefficiency and greener conversion of hypertoxic trivalent arsenic to value-added metallic arsenic.

为给深层隧道排水系统工程的主隧系统结构设计和工况控制提供依据,采用数值模拟与物理模型试验相结合的方法,建立与物理模型体型结构相同,包含两竖井和相连主隧段的主隧系统三维数值模型,利用该数值模型对两种大流量极端工况下的进水过程进行三维动态数值模拟。结果表明:主隧系统在大流量下的进水过程可归纳为水流从两端竖井进入主隧,水流碰撞形成液面波并在主隧内相互碰撞叠加,主隧下游、上游侧端口先后被封堵,以及进流停止这4个阶段;进水流量主要影响主隧系统端口封堵程度、滞气现象和进水各阶段进程时间,流量越大,主隧端口的水流封堵、滞气现象越严重,进水过程各阶段进程时间也大幅缩短。
