Afterpreconditioning, theBODsensing fil can be steadily usedfortwo onths. The 2 linear fluctuant coefficient(R ) in therangesof 0 100 gL and 0 40 gL was09950 and 09604, respectively. The effectsof activated concentration, te perature, pH, sodiu chloride concentration and coexisting etal ions to BOD deter inationwere investigated.
