20090155916 | LIQUID ANALYSER AND METHOD - A liquid analyser has a reactor portion and an associated measurement portion. A sample pump is operable to deliver a liquid sample to a reactor vessel. A base pump supplies a base solution to the reactor vessel. An ozone generator supplies ozone to the reactor vessel. The liquid sample is oxidised in the reactor vessel by means of hydroxyl radicals which are generated using the base solution and ozone to reduce complex components of the liquid sample to their lowest state in solution. The oxidised sample solution is delivered to an optical detector in the measurement portion to determine the concentration of one or more selected materials such as nitrogen, phosphorous or a heavy metal in the oxidised sample solution. | 06-18-2009 |

20100178704 | RAPID SENSING OF TOXIC METALS WITH HYBRID INORGANIC MATERIALS - Methods for rapid sensing of dissolved toxic heavy metals use a hybrid inorganic material (“HIM”), which is synthesized from hydrated iron oxide (“HFO”) and calcium magnesium silicate. HIM thus synthesized is used in sensing dissolved toxic heavy metals. Water containing toxic heavy metals (e.g., lead, copper, zinc, nickel, etc.) is passed through a sorbent bed of HIM, whereupon it shows a sharp drop in pH after a certain length of time. The presence of HFO and calcium magnesium silicates in HIM synergistically provide a precipitous drop in pH, which is characteristic of the concentration and type of toxic heavy metal. Therefore, observing a change in pH indicates the presence and identity of heavy metal ions in a test water sample. | 07-15-2010 |
