摘要:
为揭示重金属存在条件下沉积物(生物膜)吸附阿特拉津(atrazine, AT)的复合污染规律,通过编程研究筛选优化沉积物吸附AT多元回归吸附模型(atrazine-multiple regression adsorption model ,AT-MRAM),以定性变量的方式将共存的Cu2+(外因)引入模型中,建立包含Cu2+影响的沉积物吸附AT-Cu2+-MRAM.经分析发现,Cu2+的存在会抑制AT在沉积物上的吸附,且Cu2+质量浓度越大其抑制作用越强,Cu2+质量浓度为75 mg/L时的抑制程度比15 mg/L时的抑制程度提高1倍以上;Cu2+对沉积物组分(铁氧化物和有机质)的吸附能力产生一定影响,会使各组分的吸附能力减弱8.75%~19.40%.
Abstract:
In order to reveal characteristic of atrazine (AT) adsorption onto the surficial sediments (the natural surficial coating samples) in the copper/AT composite contamination system, Cu2+ (external) as a qualitative variable was introduced into the multiple regression adsorption model(MRAM), and a new AT-Cu2+-MRAM was developed. It is found that copper caused antagonistic effect on AT adsorption, the inhibition is generally enhanced with the increase of copper levels, and the inhibition with Cu2+ present at level of 75 mg/L is one time more than that with Cu2+ present at level of 15 mg/L. Also, Cu2+ can affect the AT adsorption onto the main components (such as Fe oxides and organic materials) in surficial sediments (the natural surficial coating samples), decreasing the AT adsorption onto the main components by 8.75%~19.40%.
