| 1 | 利用电阻率和探地雷达(GPR)法进行污染场地地球物理勘查——巴西圣保罗州里贝朗普雷图市润滑油废物处理区研究实例显示文摘地球物理方法在圈定废物处理区污染范围方面非常有效,有助于提高测深项目和监测井安装的效率。在研究区内,再精炼润滑油废弃物已堆积了近25年。为了开展此项研究,在该区开挖了4个总体积约25000m^3的沟槽。在沟槽底部和两侧未使用任何保护衬砌。本文目的是,评价电阻率和探地雷达法在描述巴西圣保罗州里贝朗普雷图市这种润滑油废物处理区污染的潜力,该润滑油废物处理区位于Serra Geral组玄武岩倾复带和Botucatu组砂岩的地质单元。采用二维剖面图显示方式揭示地球物理勘查结果。地球物理勘查结果表明:沟槽下部区域的电阻率(小于185Ωm)反映碳氢化合物中细菌的活动,与在以往文献中报告的由碳氢化合物引起污染的多个场地内观测结果类似。通过探地雷达法(GPR)可确定沟槽的几何形状。通过直接取样(监测井中地下水和土壤的化学分析)可证实污染的存在。在土样分析中发现,样品中存在多种低浓度的多环芳香碳氢化合物(PAH),这些化合物主要为萘和菲。通过水样分析证实地下水受到铅污染。在勘查期间使用的地球物理方法,为这种润滑油废物处理区研究提供了一种极好的环境描述手段,且在类似地区的研究中也可应用这些地球物理方法。 | Alexandre Lisboa Lago Vagner Roberto Elis 赵玉军(翻译) 武毅(校对) | 2009 | 水文地质工程地质技术方法动态2009，，3： | 3 |

| 7 | Natural Mg silicates with different structures and morphologies: Reaction with K to produce K2MgSiO4 catalyst for biodiesel production显示文摘In this work, different magnesium silicate mineral samples based on antigorite, lizardite, chrysotile(which have the same general formula Mg3Si2O5(OH)4), and talc(Mg3Si4O10(OH)2) were reacted with KOH to prepare catalysts for biodiesel production. Simple impregnation with 20 wt% K and treatment at 700–900°C led to a solid-state reaction to mainly form the K2MgSiO4 phase in all samples. These results indicate that the K ion can diffuse into the different Mg silicate structures and textures, likely through intercalation in the interlayer space of the different mineral samples followed by dehydroxylation and K2MgSiO4 formation. All the materials showed catalytic activity for the transesterification of soybean oil(1:6 of oil : methanol molar ratio, 5 wt% of catalyst, 60°C). However, the best results were obtained for the antigorite and chrysotile precursors, which are discussed in terms of mineral structure and the more efficient formation of the active phase K2MgSiO4. | Fabiane Carvalho Ballotin Mayra Nascimento Sara Silveira Vieira Alexandre Carvalho Bertoli Ottávio Carmignano Ana Paula de Carvalho Teixeira Rochel Montero Lago | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，1： | 0 |
