摘要
研究了pH、温度对铬渣中Cr3+的氧化速率的影响.结果表明,在碱性条件下,空气中的氧气具有相当强的氧化性,足以将Cr3+氧化为Cr6+,且随pH、温度的升高而加快.
The influence of pH and temperature on oxidation speed of Cr 3+ was studied in the paper.The result showed that the oxygen in atmosphere presented quite strong oxidative ability under alkali conditions.It can oxide Cr 3+ into Cr 6+ easily,and the oxidation speed increased with the rise of pH and temperature.
