森林沼泽区富含有机质样品中金的存在形式及对分析的影响

为探讨中国东北森林沼泽地区富含有机质样品中金偏低的原因,采用了王水溶矿法和四酸溶矿法的AAS分析来测定样品中的Au。用四酸溶矿法驱除硅胶,明显地提高金的测定值,特别是对含量大于10-9的样品,2种分析方法的差别更大。通过以上研究发现,在森林沼泽区的富含有机质样品中,金除以有机质结合形式存在于介质中,还可能以胶体或纳米形式存在于样品中,并被SiO₂胶体所包裹,在高浓度有机酸的保护下,金能在水溶液中呈活动形式做长距离迁移;但用王水溶矿法不能测定出这种被SiO₂胶体包裹形式的金。

银北平原浅层高砷地下水砷富集水化学特征研究

宁夏银川平原是继河套平原之后,在黄河流域发现的又一个高砷地下水分布区.为了总结其高砷地下水的水化学特征,并探索水化学因素对地下水砷释放和富集的影响机制,本文以银川平原北部（银北平原）作为典型研究区,采取野外水文地质调查、水样采集与测试、砷与水化学组分散点图相关分析及水文地球化学方法进行了综合研究.结果表明,银北平原地下水砷含量在0.2~177 μg/L之间;高砷地下水（大于50 μg/L） pH值多在7.5~8.5,水化学类型主要为HCO3-Na·Ca、Cl·HCO₃-Na及Cl·HCO₃-Na·Ca型,E_h多在-200~-100 mV.银北平原砷含量较高的地下水中COD、NH₄⁺、HCO3^-含量相应也较高,而NO3^-和SO₄^2-含量较低.高砷富有机质的冲-湖积含水层经过长期演化,形成偏碱性的中强还原性地下水环境和特殊的水化学特征,也具备极大的砷释放能力.较高的pH导致砷从铁锰氧化物或氢氧化物等水合物或黏土矿物表面解吸.其次部分铁锰氧化物在高pH、低E_h条件下可被还原为低价态可溶性铁锰,从而使与其结合的砷也得以释放进入地下水中.此外重碳酸根与砷酸根、亚砷酸根的竞争吸附行为促使含水层砷的解吸.     

昆阳磷矿磷块岩的矿物组成

昆阳磷矿是我国下寒武统最大的磷块岩矿床之一,矿层赋存于下寒武统渔户村组的中谊村段地层中(罗惠麟等,1982),矿层有上、下两层,分别称之为“上磷层”和“下磷层”,中间为一“白泥层”(含磷粘土页岩)分隔(Yeh Lien-tsun et al.,)。含磷岩系的岩性序列特征见图5。罗惠麟等认为,本段地层均为台凹相沉积,其中“下磷层”的形成环境为潮下低能及间歇性高能带,“白泥层”为潮下低能带,“上磷层”为潮下高能带,再往上则向潮间坪过渡。本文研究磷块岩的矿物组成,主要是矿石矿物磷灰石和粘土矿物的特点,并讨论磷灰石成份同矿石类型和形成环境等问题。     

山东苍峄铁矿带沟西西官庄矿区地下水微量元素 Fe^ 3＋富集赋存规律

东胜煤系砂岩型高岭土的富集机理

通过对东胜含煤地层成煤期沉积环境、古介质等的分析,并用有机吸附实验对高岭石与有机质的吸附关系进行了实验,探讨了东胜砂岩型高岭土的富集机理。结果表明,高岭石在河流环境中的富集成矿与水介质中大量有机质的存在有关,植物分解产生的腐殖质具有很强的吸附性,在pH值>5.5和适量的多价阳离子存在的条件下,介质水中的腐殖质可通过多价阳离子与高岭石和石英相互牢固吸附,形成高岭石-有机质-石英复合体,从而使高岭石能够与石英一起搬运、沉积;某些具有一定疏水性的有机质与矿物的吸附,改变了矿物颗粒表面的亲水性,促进了高岭石的沉积富集。
