预处理的铜绿假单胞菌对Cu2+的生物吸附研究

从电镀废水污泥中分离，纯化获一高抗铜菌株，经鉴定为铜绿假单胞菌（Pseudomonas aeruginosa)，采用不同浓度盐酸对铜绿假单胞菌进行预处理，同时考察了不同因素如溶液的pH，温度，摇床转速，接触反应时间对未处理菌和预处理的影响，结果表明，经0．1NHCl预处理的菌体具有最佳吸附效果，pH、摇床转速对菌体的吸附具有较显著影响，温度对菌体吸附影响不大。     

水中酚类有机污染物HPLC分析及其应用

超声辐照技术降解水中有机污染物，其降解效率的主平价需要简单、快捷和精确的分析方法。为此研究了5种优先控制酚类污染物的HPLC分离及定量分析方法，方法的定量范围为0.4-100mg/L，检测限介于0.34-0.79ng/μL。4－氯酚的超声降解实验表明，随着反应溶液中4－氯酚初始浓度的降低，降解效率明显提高，因此该方法适用于超声降解过程中酚类污染物的跟踪测定。

小诺霉素发酵废水好氧生物处理试验研究

对具有强抑制性污染物的抗生素小诺霉素发酵废水，选择活性污泥、粉末活性炭（ＰＡＣＴ）、纯氧曝气等３种好氧生物处理法进行了比较试验。根据实验结果，小诺霉素发酵废水的生物降解呈抑制动力学，采用Ｍａｒｑｕａｒｔ方法对动力学模式进行参数估计。ＰＡＣＴ能够有效地降低降解过程中微生物受到的抑制作用，从而明显地改善了生物处理过程动力学。     

直接法测定大气中的非甲烷烃

介绍了在２个监测点，用直接法测定大气中的非甲烷烃。测定方法的检出限可达０．００６５ｍｇ／ｍ＾３，在线性范围０－１０ｍｇ／ｍ＾３时，线性相关系数为０．９９９５，相对标准焦虑差为２．８％。结果表明，由于大气逆温层、工业排放源、汽车排气对非甲烷烃的浓度变化产生影响，其日变化曲线呈双峰形。     

Adsorption selectivity of salicylic acid and 5-sulfosalicylic acid onto hypercrosslinked polymeric adsorbents

Both bottle-point and column-feeding experiments involving different solutes and sorbents were carried out to investigate the adsorption selectivity and separation performance of salicylic acid and 5-sulfosalicylic acid. Their adsorption isotherms onto such hypercrosslinked polymeric adsorbents as NDA-100 and NDA-99 could be well described by the Freundlich equations whose characteristics describe extrathermic and favorable adsorption processes. The adsorption towards NDA-100 mainly depended on the π-π interaction, while that towards NDA-99 was extremely influenced by the static-electric interaction. Additionally, the adsorptive capacity of salicylic acid on NDA-99 decreased while it increased on NDA-100 with the presence of 5-sulfosalicylic acid in the adsorptive environment as the competitive component. Comparatively, the adsorption capacity of 5-sulfosalicylic acid decreased on both resins with salicylic acid as the competitive component. In fact, the difference in the interaction between adsorbent and adsorbate resulted in the straight antagonism on the effective adsorption sites on the adsorbent. In conclusion, the adsorption selectivity of salicylic acid onto NDA-100 was obviously larger than that onto NDA-99 with the existence of 5-sulfosalicylic acid in the adsorptive environment. A satisfactory separation and recovery of tested solutes in aqueous phase could be foreseeably achieved by the sequencing adsorption technique involving NDA-100 as well as NDA-99.

钱塘地区早石炭世地层和植物群

本文主要论述钱塘地区早石炭世地层和植物群。将早石炭世地层中产的植物化石分为三个组合:1.Lepidodendropsis hirmeri,Bothrodendron fuyangense组合.时代为晚泥盆世至早石炭世早期,笔者认为它是Lept ophloeum rhombicum Sublepi-dodendron mirabile组合与Lepidodendron gaolishanense Eolepidodeudraou spp.Sublepidodendron mirnbile组合之间一个过渡型组合。2.Anisopteris cf.transitionis- Archaeocalamites scrobieulatus组合。它与湘中测水组植物群为代表的韦宪中期Cardiopteridium spet sbergense-Triphyllopteris collombicum组合或C.spet sber-gense-Adiantitea gothanii组合对比。时代为早石炭世韦宪期或我国的大塘阶。3.Neuropteris schlehani f.rectinervis-Mariopteris acuta f.obtusa组合。它与江西梓山群佛岭组、广东测水组上段和忠信组中段的Archaeopteridium-Sphenopterisobtusiloba组合相当,时代为早石炭世韦宪晚期。
