要約(Abstract) :A flow injection analysis of acid-base by detecting neutralization heat is proposed. A injected sample (acid or base), combined with a carrier (deionized water), was mixed with a reagent (base or acid) stream. A change in the solution temperature was detected by passing the solution, immediately after mixing, through a stainless steel capillary tube around which a thermo-sensitive resistance was coiled. The temperature of carrier was used as a reference Hydrochloric acid solutions of 0.003 to 0.2M could be determined at a rate of 120 smples/h. Using this system, determination in weak-acid and weak-base system could also be performed. Thermo-sensitive resistances used in this work were completely free from corrosion, and effects of the ambient temperature and the sample diffusion in the detector were minimized.
