Embodiments of the present disclosure describe a method of preparing a colloidal solution comprising preparing a salted aqueous solvent and dispersing a graphitic material in the salted aqueous solvent. Embodiments of the present disclosure further describe a method of treating a graphitic material comprising agitating a graphitic material in a salted aqueous solvent and removing residual chemical species to obtain a treated graphitic material. Embodiments of the present disclosure also describe a colloidal solution comprising a liquid medium and a treated graphitic material dispersed in the liquid medium sufficient to form a colloidal solution.

Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated using a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.

Technologies relating to increasing hydraulic fracturing efficiencies in subterranean zones by degrading organic matter, such as kerogen, are described. A method for treating kerogen in a subterranean zone includes placing a composition in the subterranean zone, and the composition includes an oxidizer including sodium bromate and an additive including a tetrasubstituted ammonium salt.

A process produces salt by way of strong brine concentration after sea water desalination by using a two-way circulation method and bromine extraction. The process includes the following steps: A, preparing fresh water and strong brine from sea water in a high-pressure reverse osmosis unit by using a reverse osmosis method, wherein the concentration of the prepared strong brine is 70000 to 80000 PPM; and B, performing fresh and concentrated separation on the strong brine with the concentration of 70000 to 80000 PPM in a two-way circulation manner by using a concentration difference method till the strong brine is crystallized.
