摘要
利用乙二胺-四乙酸钠(EDTA)的反式异构体螯合阻碍废水生化需氧量准确测定的金属离子。结果表明，1 ml 0.1 m EDTA可有效螯合1升家禽废水中5 mg Cu(II)和6 mg Zn，对BOD值无抑制作用。
Use of EDTA for chelating toxic metals inhibiting BOD measurements
The trans-isomer of sodium ethylenediamine-tetraacetic acid (EDTA) was used to chelate metal ions known to inhibit accurate determination of BOD of wastewater. The results showed that as much as 5 mg Cu(II) and 6 mg Zn present in a litre of poultry wastewater were effectively chelated by 1 ml of 0·1 m EDTA so that the metals had no suppressive effect on the BOD values.
