摘要：

A new sensor based on the porous plastic probe has been developed for the detection of dissolved oxygen. This probe was prepared by co-polymerization of monomer, cross-linking reagent, porogent and luminescent ruthenium(II)diimine complex. The porous plastic probe exhibits good response to dissolved oxygen and resistance to indicator leaching out due to its high hydrophobicity. The preparation and characteristics of the probe were investigated in detail. This porous plastic probe serves as anal yte-sensitive function as well as optical wave-guide, which make it easy to assemble the fiber-optical chemical sensor (FOCS). The developed sensor has been applied to the determination of dissolved oxygen in seawater with satisfactory results compared with the standard method. (c) 2007 Elsevier B.V. All rights reserved.
