溴(Br)是化学元素之一,是一种重要的化工原料。它在国民经济中有着广泛的用途,主要用于农药、医药、航空、运输、石油、照相等。在自然界中,溴主要存在于海洋里。海水中含有的各种主要元素中,溴的含量占第七位,每立方米海水含溴约65克,其总贮量有92万亿吨。由于溴在陆地上很少,所以被誉为“海洋元素”。

Bromine (Br) is one of the chemical elements and is an important chemical raw material. It has a wide range of uses in the national economy and is mainly used in pesticides, pharmaceuticals, aviation, transportation, petroleum, and photography. In nature, bromine is mainly found in the ocean. Among the various major elements contained in seawater, the bromine content accounts for the seventh place, with about 65 grams of bromine per cubic meter of seawater and a total storage capacity of 92 trillion tons. Since bromine is rare on land, it is known as “marine elements.”
