| 摘 要： | 采用ICP-AES方法测定攀枝花尾矿库溪流水、悬浮物、沉积物中钒的含量,以及沉积物中钒的化学形态,结果表明:不同介质中钒的含量均高于全球钒的平均值;钒主要存在于沉积物及悬浮物中;水相中钒的含量主要与沉积物中钒的含量及存在形态有关;沉积物中的钒以残留态为主,各形态钒的比例主要受上覆水体理化性质的影响.

| Abstract: | A total of 11 water samples, 11 sediment samples, and 9 suspended substance samples were collected along the stream through the Panzhihua Tailing-dam. The total concentrations of vanadium in water, suspended substance and sediment were analyzed by ICP-AES method, and the chemical speciation of vanadium in the sediment was analyzed by improved BCR three-step sequential extraction procedure. In the study area, the total contents of vanadium in water, sediment and suspended substance were higher than those ave... |
