Processing of Barium Sulphide to Barium Carbonate and Sulphur

Regeneration of barium carbonate from barium sulphide in a pilot-scale bubbling column reactor and utilization for acid mine drainage.

Batch regeneration of barium carbonate (BaCO(3)) from barium sulphide (BaS) slurries by passing CO(2) gas into a pilot-scale bubbling column reactor under ambient conditions was used to assess the technical feasibility of BaCO(3) recovery in the Alkali Barium Calcium (ABC) desalination process and its use for sulphate removal from high sulphate Acid Mine Drainage (AMD). The effect of key proces...

Loss of Radioactivity From Barium Carbonate Samples.

The exchange loss of radioactivity from solid samplos of barium carbonate through the agency of carbonic acid and its ions has beon investigated under a variety of conditions. It is concluded that tho losses observed are greatly dependent upon the method of sample proparation, in particular the nature or any heat troatment which the sample materials undergo. This paper is based upon work porfor...

Barium and Barium Compounds

The International Programme on Chemical Safety (IPCS), established in 1980, is a joint venture of the United Nations Environment Programme (UNEP), the International Labour Organization (ILO), and the World Health Organization (WHO). The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, ...

A Case of Accidental Poisoning with Barium Sulphide

B. L., Hindu male, aged 55 years, took about li drachms of a depilatory powder (containing 1 part barium sulphide and 8 parts washing earth, or botni mitti) mistaking it for a laxative powder which he used to take as a home remedy, at 4 a.m. on April 14th, 1929. Vomiting commenced soon after and was persistent; he had 3 motions in the course of the next 4 hours. At 10 a.m. he noticed difficulty...
