How Is `barium `extracted?

Answer Question

Answer 1

Barium can be extracted by a simple and sensitive extraction-spectrophotometer method for the purpose of barium is reported. The 18C6-barium-Rose Bengal ternary compound was quantitatively extracted into dichloromethane, and its absorbance was calculated at 565 nm. The calibration table is linear over a barium concentration range of 0.083 - 4.70 µg ml-1. The edge of detection of barium was 17.7 ng ml-1. The comparative standard deviation (RSD) of ten copy measurements was 2.19% for a 0.83 µg ml-1 barium solution.

The interfering effects of various cations and anions were also calculated and reported. The described method provides an easy and dependable means for determination of trace amounts of barium in actual samples.

Answer 2

Barium is found in the minerals Barites, BaSO4, and Witherite, BaCO3.

For the majority element, ores hold metals in a rusty form. Apart from their mechanical preparation - crushing, grinding and screening - and their concentration by flotation, the ores have to go through a number of processing stages prior to being used or refined.

Chlorine allows the mining of several metals, including titanium. It is also used to filter valuable metals. AUPLUS hydrogen peroxide is used to detach gold from its ore, as it increases the reaction pace and the yield of the cyanization process. Caro's acid is used to corrode uranium and eliminate it from its ore. The uranium in the solution is precipitated as uranium peroxide - "yellow cake" - by the addition of hydrogen peroxide.

These two products are simple to process and have no negative environmental effects, thus making the reaction easy to control. Sodium carbonate is used for roasting (heating of the ore in a current of air) of chromium and vanadiferous compounds. Caustic soda is used for the taking out cycle of aluminum oxide from bauxite.
