    Carbon Footprint

    How often do you travel by plane?How much electricity do you use?
    These days everyone is worried about the size of their carbon footprint.In order to reduce global warming we need to make our carbon footprints smaller. But how much CO2 are we responsible for?
    A new book might be able to help.The Carbon Footprint of Everything looks at the different things we do and buy,and calculates the amount of CO2 all of the following created:the ingredients, the electricity used in the brewery,the equipment,the travel and commuting of the beer,and the packaging. It's amazing how many different things need to be included in each calculation.And it's frightening how much carbon dioxide everything produces.
    But all of this can help us decide which beer to drink.From Berners-Lee's calculations,it's clear that a pint(568ml)of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer. This is because the imported beer has been transported from far away,and it uses more packaging. The local beer only produces 300g of CO2,but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket.
    Berners-Lee has even calculated the carbon footprint of cycling to work.Nothing is more environmentally-friendly than riding a bike,surely?Well,it depends on what you've had to eat before. To ride a bike we need energy and for energy we need food.So if we eat a banana and then ride a kilometer and a half,our footprint is 65g of CO2.However,if we eat bacon before the bike ride,it's 200g. In fact,bananas are good in general because they don't need packaging,they can be transported by boat and they grow in natural sunlight.
    So,does this mean that cycling is bad for the environment?Absolutely not,for a start,if you cycle,you don't use your car,and the fewer cars on the road,the fewer traffic jams.And cars in traffic jams produce three times more CO2 than cars traveling at speed.Cycling also makes you healthy and less likely to go to a hospital. And hospitals have very big carbon footprints!
    So maybe it's time for us all to start making some changes.Pass me a banana and a pint of local beer,please.

    According to Berners-Lee,which of the following produces the most carbon dioxide?
    A:A pint of local beer we drink.
    B:A pint of imported beer we drink.
    C:A banana we eat before a bike ride.
    D:The bacon we eat before a bike ride.

    答案:B
    解析:
    细节题。根据原文可知以下产生的二氧化碳量分别是:A选项,一品脱当地酿造的啤酒为300克,B选项,一品脱进口啤酒为900克,C选项,骑车前吃的香蕉为65克, D选项,骑车前吃的培根肉是200克。
    词义推断题。第三段第二句:原料、xxx所用的电量、设备、啤酒的运输和包装。由此可知A最合理,B’选项与原文的“设备”重复了,D选项同理,C选项与包装重复了。
    推断题。从第六段可以看出骑车是环保的,产生的碳足迹是少的,其他选项都没有在原文中体现这个意思。
    推断题。第五段最后一句:香蕉总体来说是很好的,因为它们无需包装,可以使用船只运输,并且在自然光照下生长。这些都是说香蕉产生的碳足迹少,并没有提到它是健康食品。A、B、D原文均有体现。
    主旨题。本文大意是阐述了我们的碳足迹量有多少。A、B和C均只是原文中的一点。

    Lambert-Beer定律的物理意义是什么?为什么说Beer定律只适用于单色光?浓度C与吸光度A线性关系发生偏离的主要因素有哪些?

    B.eer定律的一个重要前提是单色光。也就是说物质对单色光吸收强弱与吸收光物质的浓度和厚度有一定的关系。物质对不同的单色光选择吸收,具有不同的吸收能力,非单色光吸收强弱与物质的浓度关系不确定,不能提供准确的定性定量信息。

  • 第13题:

    请说明为什么Lamber-Beer定律是吸光光度分析法的基础,引起Lamber-Beer定律偏离的主要原因有哪些?


    答案:物质对光吸收的定量关系很早就受到了科学家的注意并进行了研究。皮埃尔·布格(Pierre Bouguer)和约翰·海因里希·朗伯(Johann Heinrich Lambert)分别在1729年和1760年阐明了物质对光的吸收程度和吸收介质厚度之间的关系;1852年奥古斯特·比尔(August Beer)又提出光的吸收程度和吸光物质浓度也具有类似关系,两者结合起来就得到有关光吸收的基本定律——布格-朗伯-比尔定律,简称比尔-朗伯定律。

    “吸光光度分析方法”又称“紫外及可见分光光度法(Ultraviolet-visible Spectrophotometry, UV-Vis)”,是根据物质分子对紫外及可见光谱区的吸收特性和吸收程度,对物质进行定性和定量分析的一种吸收光谱法。全自动生化分析仪检验血液中各物质含量的分析是吸光光度分析方法的应用之一,根据分析化学中的显色反应,利用不同的生化试剂把不同物质的含量通过颜色深浅反应出来,再由郎伯-比尔定律定量分析其浓度。

    布格(Bouguer)和郎伯(Lambert)先后在1729年和1760年阐明辐射强度和吸收层厚度的关系,1852年比尔(Beer)又提出辐射强度和吸收物浓度也具有类似的关系,这便是著名的布格-郎伯-比尔定律。比尔定律的数学表达式为:

    A= = bc (2-1)

    式中,A为吸光度,I0为入射辐射强度,It为透过辐射强度,b为吸收层厚度(cm),C为吸收物的摩尔浓度(M),ε为摩尔吸光系数(L﹒mol﹒cm)。此定律广泛应用于紫外-可见-红外光谱区吸收测量,全自动生化分析仪中各项生化指标的检验也依据于此定律。

    在分光光度分析中,比尔定律是一个有限的定律,其成立条件是待测物为均一的稀溶液、气体等,无溶质、溶剂及悬浊物引起的散射;入射光为单色平行光。导致偏离朗伯-比尔定律的原因很多,但基本上可分为物理和化学两个方面。物理方面主要是入射光的单色性不纯所造成的;化学方面主要是由于溶液本身化学变化造成的。

    1、单色光不纯引起的偏离

    严格说来,朗伯-比尔定律只适用于单色光。但由于仪器分辨能力所限,入射光实际为一很窄波段的谱带。由于分光光度计分光系统中的色散元件分光能力差,即在工作波长附近或多或少含有其他杂色光,杂散光(非吸收光)也会对比尔定律产生影响,这些杂色光将导致朗伯-比尔定律的偏离。实际上,理论上的单色光是不存在的,我们所做的只能是让入射光的光谱带宽尽可能的小,要尽可能的靠近单色光。

    2、溶液性质引起的偏离

    样品溶液浓度的影响:

    比尔定律是一个有限的定律,它只适用于浓度小于0.01mol/L的稀溶液。因为浓度高时,吸光粒子间的平均距离减小,受粒子间电荷分布相互作用的影响,他们的摩尔吸收系数发生改变,导致偏离比尔定律。因此,待测溶液的浓度应该控制在0.01mol/L以下。

    3、溶质和溶剂的性质

    例如,碘在四氯化碳溶液中呈紫色,在乙醇中呈棕色,在四氯化碳溶液中即使含有1%乙醇也会使碘溶液的吸收曲线形状发生变化。这是由于溶质和溶剂的作用,生色团和助色团也发生相应的变化,使吸收光谱的波长向长波长方向移动或向短波长方向移动,即所谓的红移和蓝移。

    4、介质不均匀性

    朗伯-比尔定律是适用于均匀、非散射的溶液的一般规律,如果被测试液不均匀,是胶体溶液、乳浊液或悬浮液,则入射光通过溶液后,除了一部分被试液吸收,还会有反射、散射使光损失,导致透光率减小,使透射比减小,使实际测量吸光度增大,使标准曲线偏离直线向吸光度轴弯曲,造成对朗伯-比尔定律的偏离。

    所以,在分析条件选择时,应考虑往样品溶液的测量体系中加入适量的表面活性剂等来改善溶质的均匀度。

    5、溶质的变化

    比尔定律在有化学因素影响时不成立。解离、缔合、生成络合物或溶剂化等会对比尔定律产生偏离。离解是偏离朗伯-比尔定律的主要化学因素。溶液浓度的改变,离解程度也会发生变化,吸光度与浓度的比例关系便发生变化,导致偏离朗伯-比尔定律。

    溶液中有色质点的聚合与缔合,形成新的化合物或互变异构等化学变化以及某些有色物质在光照下的化学分解、自身的氧化还原、干扰离子和显色剂的作用等,都对遵守朗伯-比尔定律产生不良影响。

    来自出射狭缝的光,其光谱带宽度大于吸收光谱带时,则投射在试样上的光就有非吸收。这不仅会导致灵敏度的下降,而且使校正曲线弯向横坐标轴,偏离朗伯-比尔定律。非吸收光越强,对测定灵敏度影响就越严重。并且随着被测试样浓度的增加,非吸收光的影响增大。当吸收很小时,非吸收光的影响可忽略不计。
