Abstract
Bismuth(III) nitrate (Bi(NO3)3) has pharmaceutical applications and is usually produced from elemental bismuth dissolution in nitric acid (HNO3). However, if bismuthinite (Bi2S3), which is one of the main minerals of bismuth, is used to produce elemental bismuth, sulfur dioxide (SO2), carbon monoxide (CO), and nitrogen oxides (NOx) are produced, which are three of the air pollutants considered the most serious threats to human health and welfare. This communication takes a thermodynamic approach to examine and then suggests an environmentally friendlier procedure to produce Bi(NO3)3: the direct dissolution of Bi2S3 in 1 M HNO3 at room temperature (25 °C).
硝酸铋（III） （Bi(NO3)3）具有制药应用，通常由元素铋在硝酸（HNO3）中溶解产生。然而，如果用铋矿（Bi2S3）（铋的主要矿物之一）生产单质铋，就会产生二氧化硫（SO2）、一氧化碳（CO）和氮氧化物（NOx），这三种空气污染物被认为是对人类健康和福祉最严重的威胁。本文采用热力学方法进行研究，然后提出了一种更环保的生产Bi(NO3)3的方法：在室温（25°C）下，将Bi2S3直接溶解在1 M HNO3中。
