Introduction
氢能够同时具有多种同位素,氘似乎是其同位素之一。它包含一个中子和一个质子作为其关键成分。由于氘中存在中子,它看起来比氢的其他同位素更重。这种同位素在聚变反应堆、军事和科学领域有一些实时用途,最终使其成为有用的氢同位素之一。
What is Deuterium?
氘是氢的一种同位素,其原子核中含有一个中子和一个质子。这种同位素的特殊性在于它的质量,因为它的质量是普通氢的两倍。由于它由一个中子组成,质量自动变为两倍,最终使其比氢的其他同位素更重(Merriam-webster,2022)。由于其质量是原来的两倍,重量更重,这种氢同位素被称为重氢
Figure 1: Deuterium
氘以重水的形式出现,数量非常少,尤其是在海洋中,但它们极难提取。氘的原子核通常被认为是氘或氘,其化学符号为2H或D。该成分的原子量约为2.014,是氢的较重同位素之一
Figure 2: Structure of Deuterium
这种同位素是一种稳定的原子,可以在天然氢中找到。这种氢气在一定程度上有助于天然氢气的形成过程,因为在氢气形成过程中存在0.0156%的氢气。与其他同位素不同,氘没有放射性,在海水中的含量为156.25ppm(Karasiev等人2019)。海洋中氘的存在几乎等于氢原子的大小,实时约为6.400。
Properties of Deuterium
氘有一些重要的特性,使其在实时情况下与其他氢同位素不同。氘的第一个特性是它的重量,这首先为它赢得了重氢的名字。氘结构中存在的中子使其比其他氢同位素(如质子)更重。氘能够形成比普通氢更强的化学键。它比普通氢有更高的三点和更高的沸点。此外,氘的聚变热和蒸发热更高,这使其能够实时施加比常规氢气更大的蒸汽压
Figure 3: Properties of deuterium
氘在大多数时候都是无色的,但当它被电离时,它会发出独特的粉红色。氘的密度比传统的水高得多,因为它有更强的连接。当常规水的密度为1.624g/cm3时,氘的密度表现为10.6g/cm3
由于氘的结构中存在中子,氘的粘度比普通氢高。此外,根据氘的化学性质,氘是天然易燃无毒的。它发出淡蓝色的火焰,能够耗尽大气中的氧气水平。 这进一步使得同位素有时会在大气中引起窒息。从本质上讲,氘是一种无腐蚀性的同位素,当它被置于低温环境中时,它会溶解在水中,尤其是冷水中。此外,氘是氢的一种独特同位素,具有广泛的特征,有利于在日常生活中多次实时使用。 氘广泛应用于人类日常生活的多个领域,从人体到商业用途的机械。首先,氘被用于磁共振波谱,作为其关键成分之一。此外,它还用于稳定磁共振波谱中磁场的维持。同位素在核反应堆中也是一种有效的减速剂。在人体内,它通过确定代谢率和植物来提供帮助;它被用作光合作用的主要示踪元素(Sessions&Murph,2021)。此外,在化学领域,这种同位素用于确定不同有机化合物的同位素结构。 氘是氢的一种较重同位素,在人类日常生活中是一种极其有用的化学成分。氘的化学键比普通的氢强得多。同样,在其结构中存在一个中子使氘成为氢的更重同位素。由于连接更强,这种同位素具有更好的密度,最终使其对核反应堆有用。总之,可以说氘是氢的有用同位素之一,在化学领域具有良好的性质和强大的联系。 Q1.如何实时去除水中的氘 氘由铂催化剂组成,该催化剂在从水中去除氘方面既高效又快速。这个过程可能需要冷热结合的温度来实时分离常规水和氘。 Q2.氘的存在会引起爆炸吗 就在附近引起上部爆炸而言,氘和氢一样具有爆炸性。由于氘的共同性质很像普通的氢,它们在某些条件下似乎都是爆炸性的。 Q3.氘是一种化学毒性成分吗 答:不,氘不是有毒成分,人体自然含有氘来维持体内水分的平衡。对人类来说,小剂量饮用也是安全的,而且看起来和普通的水完全一样。Usage of Deuterium
