Water Soluble Oxygen Sensor

As dissolved oxygen concentrations are affected by temperature pressure and salinity these parameters need to be accounted for 7.

Water soluble oxygen sensor.

39 hach 146900 dissolved oxygen test kit model ox 2p. The optimum oxygen sensor film composition was 2 in 1 1 silamine mc which had an oxygen sensitivity of 0 502 over an atmospheric pressure range of 0 007 45 psi. It is also effective in river monitoring intake protection fish farming and other fields where water quality is important. The absorption maximum near 480 nm long lifetime and large stokes shift allow this probe to be used with simple instrumentation based on a light emitting diode light source allowing low cost oxygen sensing in aqueous solutions.

Temperature sensitivity percentage loss of intensity per c of this film was determined to be 1 1 and 1 4 c 1 at vacuum and 1 bar atmospheric pressure respectively. The procedure of metalloporphyrins immobilization. New materials for optical oxygen sensors based on cationic water soluble pd ii pt ii and rh iii porphyrins immobilized in perfluorinated ion exchange membranes are proposed. Because the sensor concentration would not be important the sensor could be added using a simple dropper bottle.

We developed a water soluble luminescent probe for dissolved oxygen. The compound dpp is 4 7 diphenyl 1 10 phenanthroline and dpp so3na 2 is a disulfonated derivative of the same ligand. For instance water samples could be mixed with small amounts of a water soluble sensor and the oxygen concentration determined from the intensity or preferably the decay time which would be insensitive to the probe concentration. 30 apera instruments optical dissolved oxygen meters 4 price 92.

To the best of our knowledge this is the first practical water soluble oxygen sensor. A dissolved oxygen meter water quality sonde or data logging system can be used to record measurement data taken with a do sensor. The do30g sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works effluent activated sludge process and potable water treatment. Here we report on the pl properties of water soluble cdte ncs with 3 mercaptopropionic acid as the ligand showing that these ncs are capable of responding reversibly to an inter switching of the.
