This measuring method measures the BOD of water in such a way that chlorates such as sodium chlorate or the like together with thioallyl urea added to a diluted sample, and that the oxidation of ammoniacal nitrogen and the oxidation of the nitrous nitrogen are prevented. 希釈されたサンプルに、チオアリル尿素とともに塩素酸ナトリウム等の塩素酸塩類を添加し、アンモニア性窒素の酸化および亜硝酸性窒素の酸化を防止しつつBOD測定を行う。 - 特許庁
A sample dilution means 1, a first addition means 2 which adds the thioallyl urea, a second addition means 3 which adds the chlorates, a sample propagation means 4, a dissolved-oxygen-concentration measuring means 5 and a computing means 6, constitute this apparatus. なお本発明の装置は、サンプル希釈手段1と、チオアリル尿素を添加する第1の添加手段2と、塩素酸塩類を添加する第2の添加手段3と、サンプル培養手段4と、溶存酸素濃度測定手段5と、演算手段6とからなる。 - 特許庁
