| 中文摘要 |
| 通过降解,吸附及土柱淋滤试验等手段.对选矿废水中醚胺的降解规律,降解能力,吸附能力,分配特征以及在土壤中的垂直迁移规律等环境化学特性进行了试验研究.结果表明:①醚胺在水体中的降解规律服从一级生物化学反应方程c=c-coexp(-Kt),温度和pH值是影响降解系数K的两个主要因素;②土壤对醚胺的吸附率在92%以上,吸附方程为q=5.335+63.2gc;③醚胺在土壤中的垂直迁移规律为c=aexp(-b/t). |

| Some tests have been made on soil-column leach, degradation and adsorption to study some environmentally chemical natures of the ether amines R-O-(CH2)3NH2 in mineral separation wastewater.The results indicated that:(1) in water, the R-O-(CH2)3NH2 was degraded by following an equation of first-order biochemical reaction, c-coexp(-Kt), where the temperature and pH value are two major, factors affecting the degradation coefficient; (2) the soil adsorbed the ether amines R-O-(CH2)3NH2 at a rate of over 92% and the adsorption equilibrium equation was q=5.335+63.29C; and (3) in soil, the ether amines R-O-(CH2)3NH2 moved in the vertical direction by following the c=aexp(-b/t).These results provided a scientific basis for water quality calculation and environmental protection designing. |
