The visible light absorption curve and heat recovery curve of mercuric and zinc dithizone in PMMA and PS are also measured. 测定了两种金属双硫腙在聚合物介质中的基态及激发态可见光谱吸收曲线，及其在黑暗环境下的热回复曲线。
In this paper a column chromatographic preconcentration method using dithizone supported on naphthalene for copper in natural water is provided. 本文利用吸附有双硫腙的微晶萘作富集柱富集天然水中痕量铜，甲酰二甲胺洗脱，火焰原子吸收光谱法测定。
