Abstract

A highly sensitive method is proposed to determine copper(II) ions by forming a stable complex through their interaction with 4-(2′-benzothiazolylazo)-salicylic acid (BTAS) at room temperature and pH of about 5. 0. The complex gave a maximum absorption at λ = 485 nm with a molar absorptivity coefficient of 2. 35·10⁴ l/(mol·cm). The linear range for the copper determination is 0. 63-5. 04 mg/l. The method can be applied to determine copper ions in different biological specimens like some drugs and water samples.
