少量の鉄シアノ錯体溶液などは、ほうろう引きの浅いバットに入れ、数日間直射光に晒すと分解して水酸化鉄になる。塩化鉄溶液を滴下して紺青が生じなければ、分解終了。
Even so, in comparison to inhaled cyanide exposure, where apnea is amongst the 1st symptoms, the onset of symptoms of oral cyanide exposure isn't speedy. Also, individuals ingesting cyanide can be unaware they are now being poisoned and as a consequence likely to take in larger sized amounts prior to establishing symptoms [18].

The picture is revealed and stabilized in this way, shedding its sensitivity to light-weight. Although several modern day soaked plate photographers select sodium thiosulfate or other considerably less hazardous fixers, KCN remains employed.
シアン化ナトリウムと同じく、遷移金属と反応して水に可溶なシアノ錯塩を形成する性質をもつ。この反応のため、銀や銅のさび落としに使うことができる。また、銅貨を用いたシアンの簡易検出法の原理でもある。
You will discover medical tests to evaluate blood and urine levels of cyanide; nonetheless, tiny amounts of cyanide are always detectable in blood and urine.
