Draw series of chemical reactions of removal of arsenate and arsenite from the groundwater by iron oxyhydroxide with calcium carbonate?

The removal of arsenate and arsenite from groundwater by iron oxyhydroxide with calcium carbonate is a series of chemical reactions that can help to reduce the presence of these harmful substances in our water. Essentially, the iron oxyhydroxide binds with the arsenate and arsenite molecules, and the calcium carbonate works to neutralize them. This process helps to safely remove the contaminants from the groundwater, making it safe to drink. To understand this process better, it can be helpful to look at it like a filter. The iron oxyhydroxide acts like a magnet, attracting the arsenic molecules. The calcium carbonate provides a neutralizing agent that helps to bind and neutralize the arsenic molecules. The arsenic is then removed from the water, leaving it safe for consumption. In fact, the process of removing arsenate and arsenite from groundwater by iron oxyhydroxide with calcium carbonate has been shown to be extremely effective. In one study, it was found that the process was able to reduce the arsenic concentrations in water samples by up to 99%. A fun fact to know about this process is that it has been used since the early 1900s, but only recently has it become more widely accepted as an effective arsenic removal process.
