【摘要】 本文研究了发酵废渣黑根霉菌对Ｐｂ（２＋）的吸附作用．结果表明，发酵废渣黑根霉菌对Ｐｈ２＋有较好的吸附能力．在ｐＨ３～６．５范围内，吸附能力最强．用海藻酸钠有粉末状黑根霉菌包埋成形后，机械性能较好．流速对动态吸附有很大影响，当流速为０．２７５ＢＶ／ｍｉｎ时，吸附率达８３．６％，饱和吸附量可达４９ｍｇ／ｇ．用２０％ＣａＣｌ２溶液可以洗脱和再生．本文研究结果为发酵废渣黑根霉菌的工业应用提供了基础数据．更多还原

【Abstract】 This paper reports the adsorption of Pb2+ from solution by using pharmaceutical fermentation waste Rhizopus nigricans which can be entrapped by sodium alginate. Experimental results showed that the efficiency of adsorption of Pb2+ was 83. 6% with a flow rate of 0. 275 BV/min and the saturation capacity was 49mg/g. The adsorbent can be regenerated with 20% CaCl2 solution.更多还原
