Rapid determination of Ba isotope compositions for barites using

This study presents a rapid and simple method of high precision Ba isotope measurement for barite using H2O extraction. The main challenge for analyzing the Ba isotope composition of barite is how to digest barite into solution for chemical purification. We used H2O as a dispersant to rapidly extract ∼20–75Both barite from leaching solution and barite from CAS were purified by DTPA dissolution and reprecipitation (DDARP) method twice (Bao, 2006; Crockford et al., 2018).

Isolation and Purification of Sulfate-Reducing Bacteria

Sulfate-reducing bacteria (SRB) are a widespread group of microorganisms that are often isolated from the anoxygenic environments (lake depths, soil, or swamps), and they are also present in the human and animal intestines. This group is often detected in patients with inflammatory bowel disease, including ulcerative colitis. The method was successfully applied to four natural barite-rich samples with BaSO 4 content ranging from 18.87 wt% to 42.41 wt%. Overall, this accurate and rapid method shows great potential for the precise determination of the REE content in Ba-rich samples by ICP-MS.An efficient method for the separation of REEs from Ba for the
