Heterogeneous alternative catalysts: A bibliometric and systematic evaluation of their application in solar photocatalytic processes

The present study sought to objectively demonstrate how a researcher can, in a structured way, select relevant articles about alternative heterogeneous catalysts in photocatalytic processes. Therefore, the ProKnow-C (Knowledge Development Process – Constructivist) method was used to systematize the results found, with the application bibliometric and systematic analysis techniques for the evaluation of the results. The search string adopted as criteria was: solar photocatalysis AND heterogeneous catalysts OR alternative catalysts AND effluents. The databases were Web of Science, Science Direct and Scopus. The final bibliographic portfolio obtained for the research theme was made up of 19 articles. It was possible to verify advances in the number of publications on the theme over the evaluated period, with the Journal of Photochemistry and Photobiology A: Chemistry standing out in the final portfolio. Evaluating each article in the portfolio individually, it was possible to verify that most studies use combinations of catalysts already reported to create an alternative material to those already investigated in the literature. Those that use waste as catalysts chose to source this material from treatment plants and the steel industry. Around 58% of the papers used hydrogen peroxide in their processes, while 42% chose not to use it. Finally, approximately 63% of the papers in the portfolio used synthetic effluent in their processes, while the rest (37% of the research) chose to use real effluent. The results obtained in this research by applying the method can contribute to studies related to heterogeneous photocatalysis by alternative means over the years.

火灾规律双重性模型及其对室内漏油火灾的分析

火灾的规律具有双重性:确定性和随机性。只有既研究其确定性又研究其随机性,并进而研究二者的综合才能完整地认识火灾的规律。本文提出火灾双重性规律的学术思想,通过构造室内漏油火灾的确定性和随机性模型,阐明运用火灾双重性规律表述火灾过程的具体方法。文中用微机实施的大量计算表明,该模型能方便地预言:发生室内漏油火灾时,室内设备是否会损坏以及可能被损坏的概率.     

反硝化真菌-细菌优化组合及其脱氮能力研究

从多种真菌中筛选到3株脱氮活性较高的真菌,并将其与一株从武汉市郊新筛选分离到的具有较强脱氮能力的细菌HS-03进行混和培养,通过正交实验确立其最佳培养条件。正交实验方差分析表明:碳源、pH值和温度3个因素对脱氮率的影响都非常显著,菌种因素对脱氮率有一定影响。实验结果表明,真菌与细菌混合脱氮的最佳培养条件为:以琥珀酸钠为碳源,NaNO3为N源,C/N为10,pH=7.5,温度30℃。细菌HS-03和真菌Fusariumoxyspurum的组合优于其它组合。在最佳培养条件下,该组合能在21h内去除10mmolNO3-,优于相同条件下细菌HS-03或真菌F.oxyspurum的反硝化能力。

我国南方主要酸沉降区临界负荷研究

以马尾松为指示植物,对韶关的土壤进行了长期淋溶模拟并记录其化学状态。结果发现,土壤溶液的pH值下降到4.0,Bs值下降到几乎为零,有较大量的A1离子溶出。最后选取土壤溶液pn〉4.0、KS〉10％和[Al^3＋]〈0.1mmol／L为临界化学指标,参考国内外应用广泛的MAGIC模型和SMART模型,确定韶关酸沉降临界负荷（S的临界负荷）为14.1keq／hm^2.a。     

关于完善环境污染损害赔偿法律救济的思考

随着经济的飞速发展,环境污染的现象日益严重。目前我国解决环境污染损害赔偿责任纠纷的方式包括两种,即行政处理和诉讼解决。我国环境污染损害赔偿制度尚不完善。本文就完善环境污染损害赔偿法律救济提出具体建议,即修改、完善环境污染损害赔偿相关法律制度,使其适应经济和社会可持续发展的需要。
