以巯基泥炭为分离富集剂 ,对重金属离子的单组分或多组分溶液进行吸附研究 ,探讨了吸附剂的吸附性能、影响吸附因素和吸附机理。实验表明 :巯基泥炭是一种价廉、高效的重金属固体吸附剂 ,在pH =5 ,低温下较未处理泥炭吸附量提高 5倍左右 ;对重金属离子的吸附均表现出Langmuir特征。
Adsorption of one or more components of heavy metal ions was studied by using thiol peat as enrichment agent. The adsorption properties of adsorbent were discussed, and the adsorption factors and adsorption mechanism were discussed. Experiments show that: the mercapto peat is a cheap and efficient heavy metal solid adsorbent, adsorption of peat at pH = 5, compared with untreated peat increased by 5 times; for heavy metal ions showed Langmuir characteristics.
