On the remediation potential of Vetiveria zizanioides on the water polluted with prometryn

  • 摘要:   目的  探究香根草Vetiveria zizanioides对扑草净污染水体的修复潜力。  方法  采用温室水培模拟实验的方法,研究香根草对水体不同初始质量浓度(1.0、5.0、10.0、15.0 mg·L−1)扑草净的吸收和去除特征。  结果  相同培养时间下,随水体扑草净初始质量浓度增加,香根草茎叶和根系扑草净质量分数显著增加(P<0.05),在第5天达到最大值,之后呈波动下降趋势;随培养时间延长,水体扑草净质量浓度显著降低(P<0.05)。与未种植香根草相比,香根草种植组水体扑草净降解半衰期缩短了14.80~19.78 d,去除率提高了22.52%~55.57%。相关性分析表明:水体扑草净质量浓度与香根草转移系数呈极显著负相关(P<0.01),与相对去除率相关性不显著(P>0.05),与培养时间呈极显著正相关(P<0.01)。  结论  种植香根草可提高水体扑草净降解速率和去除率,香根草可作为扑草净污染水体修复的先锋植物。图2表4参31

摘要:   目的  探究香根草Vetiveria zizanioides对扑草净污染水体的修复潜力。  方法  采用温室水培模拟实验的方法,研究香根草对水体不同初始质量浓度(1.0、5.0、10.0、15.0 mg·L−1)扑草净的吸收和去除特征。  结果  相同培养时间下,随水体扑草净初始质量浓度增加,香根草茎叶和根系扑草净质量分数显著增加(P<0.05),在第5天达到最大值,之后呈波动下降趋势;随培养时间延长,水体扑草净质量浓度显著降低(P<0.05)。与未种植香根草相比,香根草种植组水体扑草净降解半衰期缩短了14.80~19.78 d,去除率提高了22.52%~55.57%。相关性分析表明:水体扑草净质量浓度与香根草转移系数呈极显著负相关(P<0.01),与相对去除率相关性不显著(P>0.05),与培养时间呈极显著正相关(P<0.01)。  结论  种植香根草可提高水体扑草净降解速率和去除率,香根草可作为扑草净污染水体修复的先锋植物。图2表4参31
