【摘要】 采用原子吸收光谱法测定了电解锰废水及水底沉积物中主要 9种重金属元素 (Cu ,Zn ,Pb ,Cd ,Fe ,Co ,Ni,Mn ,Cr)的含量 ,阐述了它们的含量与距污染源的距离、水的流速情况及水系的多少这三者之间的密切关系 ,并寻求出这 9种重金属元素的一些规律 .更多还原

【Abstract】 This paper reveals (a) dertermin the contents of eight kinds of heavy metal element (Co,Cu,Cd,Pb,Fe,Zn,Ni,Mn)in the waste water and deposit from the electro manganese plant by Flame Atomic Absorption Spector. (b) study the relaton of the contents, distance from the pollution and speed of water, thus conclude some disciplin of transter about the eight heavy metal element.更多还原
