长江中下游海相三叠系膏盐层与铜(金)、铁矿床

长江中下游海相三叠系膏盖层中含有很大比例的大、中型铜（金）、铁、多金属矿床。膏盐层不仅是铜（金）、铁矿床的主要赋矿层位之一，而且是部分成矿金属的矿源层；膏盐层还为燕山期岩浆提供部分钠质、钾质及挥发组分，影响岩浆演化的方向，改变了含矿流体的性质；另外，从岩体和矿床中金属硫化物中流同位素重硫成分的增高，说明在成者、成矿过程中，膏盐层是硫的供应者之一。因此膏盐层与铜（金）、铁、多金属矿床之间存在着特殊的成因联系。

灰色聚类法在许昌市中浅层地下水质评价中的应用

运用灰色聚类法对许昌市中浅层井水水质进行分级评价。结果表明：77％的中浅井水水质尚好，基本上没受到污染，各项指标的综合评价结果接近Ⅰ级水质标准；17％的中浅井有1—2项评价因子略超出生活饮用水卫生标准，综合评价结果接近Ⅱ级水质标准；6％的中浅井水不适合饮用。灰色聚类法的评价结果与模糊数学的评价结果相比较，信息的利用率、分辨率均要高些。

On-line optical determination of floc size of Fe(Ⅲ) coagulants

This study investigated the floc aggregation, average floc size, floc size variance and floc growth velocity when ferric chloride （FeCl3） and polyferric chloride （PFC） were used to treat the simulated water samples. The factors including coagulant dose, ionic strength and solution pH, which affect the floc aggregation, were studied. Experiments were carried out in a bench-scale reactor using photometric dispersion analyzer （ PDA）. Results showed that there were great differences between the floc aggregation of PFC and FeCl3. The average floc size and fioc growth velocity of PFC were much larger than those of FeCl3. Compared with FeCl3, PFC gave a better coagulation performance in wider range of pH, dosage and ionic strength. It was also found that the coagulation efficiency of PFC did not depend on average floc size but on floc growth velocity.

Catalytic dechlorinafion of o-chlorophenol by nanoscale Pd／Fe

Transformation of chlorophenols by nanoscale bimetallic particles represents one of the latest innovative technologies for environmental remediation. Nanoscale Pd/Fe bimetallic particles were synthesized in the laboratory for treatment of o-chlorophenol. Most of the nanoscale particles are in the size range of 20-100 nm. BET specific surface area of the nanoscale Pd/Fe particles is 12.4 m2/g. In comparison, a commercially available Fe powder( < 100 mesh) has a specific surface area of just 0.49 m2/g. Batch experiments demonstrated that the nanoscale Pd/Fe bimetallic particles can effectively dechlorinate o-chlorophenol. Dechlorination efficiency is affected by the mass fraction of Pd in the bimetal, nanoscale Pd/Fe mass concentration and mixing intensity.
