Abstract
For the preparation of pH-selectrode, tribenzylamine, polyvinylchloride, dioctylphthalate, sodium tetraphenylborate and tetrahydrofuran were mixed with 0.02, 0.62, 1.34, 0.02g and 10ml respectively, and added 1g of acetylene black, graphite, silicon carbide or tungsten carbide respectively to improve electric conductivity. The selectrodes of seven kinds were shown linear to hydrogen ion in the range of pH 2 and 9. The best electric conductor for preparation of pH-selectrode based on tribenzylamine as neutral carrier was acetylene black and responded potential of the selectrode to hydrogen ion was shown the values near to theoretical Nernstian slope at
수소이온 선택성 막전극을 제조하기 위하여 tribenzylamine, polyvinylchloride, dioctylphthalate, sodium tetraphenylborate와 tetrahydrofuran을 0.02, 0.62, 1.34, 0.02g, 10mL씩 섞고 전기전도도를 개선하기 위하여 acetylene black, 흑연, 탄화규소, 탄화텅스텐을 각기 1g씩 섞었다. 7개의 막전극은 pH 2~9 범위내에서 수소이온에 직선성을 나타내었다. Tribenzylamine을 중성 운반체로 사용한 수소이온에 선택성 막전극을 제조하기 위해 섞은 것 중 가장 좋은 전기전도체는 아세틸렌블랙이었다. 이 막전극은
