Optical fiber sensors have been developed to determine the concentrations of dissolved oxygen(DO) and pH value in chemical and bioprocesses. In this work, Rudpp(tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II)) as a DO sensitive fluorescent dye and HPTS (8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt) as a pH sensitive fluorescent dye were attached separately on the tip of a bundle optical fiber for fabricating the DO/pH optical fiber sensor by using MTMS (methyl trimethoxy silane) and the mixture of GPTMS(3-glycidoxypropyl trimethoxy silane) and APTMS (3-aminopropyl trimethoxy silane) as their support materials respectively. This sensor could analyze the concentrations of DO and pH in simulation processes in the DO range 0-100% and pH range of 4.0-8.0.
