General description
双硫腙（Diphenylthiocarbazone）可用作锌的螯合剂。 由于它可与金属形成稳定的络合物，因而广泛用于各种金属的液-液和固相萃取中。
Application
双硫腙（Diphenylthiocarbazone）可用于体外分化胚胎干细胞培养中分化胰岛簇的表征，因为它与胰岛中大量存在的锌形成螯合物，从而选择性染色。在用火焰原子吸收法对银进行痕量级别定量之前，可在浊点预浓缩步骤中与银离子形成络合物。

In this work, a new coupling of spectrophotometric determination with preconcentration method named as ultrasound-assisted emulsification dispersive liquid-liquid microextraction (UAE-DLLME) for trace silver was firstly established. Disperser solvent in traditional DLLME was substituted by ultrasound-assisted emulsification, which could afford more
