摘要： The invention provides a method of efficiently removing selenium from water. The method involves: adding an oxidant to the liquid, adjusting the liquid's pH to below 7.5, adding ferric salt in an amount such that less than a quarter of selenium in the liquid precipitates poly dithiocarbamate material (in ppm) is greater than the amount of ferric salt (in ppm). This method removes far more selenium than previous methods, and does it using a smaller amount of expensive chemicals. Moreover this method makes it far more likely to achieve cost effective compliance with the ever-increasing environmental standards for selenium in water.
摘要翻译：本发明提供了一种有效地从水中除去硒的方法。该方法包括：向液体中加入氧化剂，将液体的pH调节至7.5以下，加入三价盐，使得少于四分之一的液体中的硒沉淀聚二硫代氨基甲酸盐物质（ppm）大于铁盐（ppm）。这种方法比以前的方法去除了更多的硒，并且使用较少量的昂贵的化学品。此外，这种方法使得更有可能实现成本有效地符合不断增加的硒在水中的环境标准。

摘要： The reaction of halo-boron compounds (B-X compounds, compounds having one or more boron-halogen bonds) with silanes provides boranes (B-H compounds, compounds having one or more B-H bonds) and halosilanes. Inorganic hydrides, such as surface-bound silane hydrides (Si-H) react with B-X compounds to form B-H compounds and surface-bound halosilanes. The surface bound halosilanes are converted back to surface- bound silanes electrochemically. Halo-boron compounds react with stannanes (tin compounds having a Sn-H bond) to form boranes and halostannanes (tin compounds having a Sn-X bond). The halostannanes are converted back to stannanes electrochemically or by the thermolysis of Sn-formate compounds. When the halo-boron compound is BCI 3 , the B-H compound is B 2 H 6 , and where the reducing potential is provided electrochemically or by the thermolysis of formate.

摘要： A device and method for reducing and/or preventing fouling of a sensor is disclosed. The method comprises operating ultrasound technology that is submerged or partially submerged into a liquid medium that is responsible for the fouling. The device comprises the ultrasound technology itself. The ultrasound technology may be operated intermittently at high intensity to advantageously provide cavitation of the liquid medium, while avoiding the disadvantages typical of continuously operating ultrasound technology at high intensity. Additionally, the method may be carried out by taking advantage of the piezoelectric property of quartz.

摘要： The invention provides methods and compositions for separating metals from a liquid medium, the method uses a copolymer derived from at least two monomers: acrylic-x and an alkylamine, wherein said polymer is modified to contain a functional group capable of scavenging one or more compositions containing one or more metals are disclosed. The treated liquid is then passed through a filtration system. The scavenging effect of the combination of the treatment with the filtration is unexpectedly greater than the sum of its parts. MS
