A novel dithiourea and its response to metal ions

Fund Project: We are grateful for the financial supports from National High-Tech Research and Development Plan of China (No. 2007AA06Z122), National Basic Research Program of China (No. 2007CB613602) and National Natural Science Foundation of China (Nos. 51074183 and 50604016).

The synthesis, characterization, and its response to metal ions of a novel thiourea N, N'-diethoxycarbonyl-N'', N'''-(1, 2-ethylidene) dithiourea was reported. The results show that this dithiourea with new structure can react with Cu²⁺ and Ni²⁺ separately, and has a best selectivity to Fe³⁺ ions. Bench-scale flotation tests were also carried out, verifying it has higher copper flotation recovery and better selectivity to sulfide ores containing Cu compared with universal collectors.
