Preparation of Bacterial Adsorption Polymer and Its Application to Biosensors
Polymer particles immobilizing poly(N-benzyl-4-vinylpyridinium bromide) on their surfaces were prepared via reaction of a base polymer containing chloromethyl groups with poly(vinylpyridine), followed by quaternization with benzyl bromide. The polymer particles exhibited high adsorptive activity for microorganisms. A BOD sensor was prepared by a combination of a column packed with the polymer particles carrying activated sludge with an oxygen electrode. BOD values obtained using the BOD sensor agreed with those determined by the standard method.
