The researchers' method uses affordable reagents that change color in response to shifts in alkalinity. These color changes are then captured via smartphone cameras, with images processed by ...

Approximately 80 mL of brine, seawater, or brackish water sample is taken in a beaker using a pipette. Employing the Unitrode, titration is then carried out using HCl with 0.1 mol/L concentration ...

With the alkalinity from the titrator and the pHs from Jami’s work with the spec, we now have a much more detailed picture of the state of the seawater in each of our tanks than we would only with the ...

A novel machine learning approach accurately predicts water alkalinity using smartphone-captured color changes induced by low-cost reagents. The technique demonstrates strong performance across ...

By increasing the alkalinity of seawater through the addition of certain minerals (e.g., carbonates and silicates), the ocean can chemically bind more CO 2 without further acidification.

Ocean alkalinity enhancement is a proposed method of removing excess carbon dioxide from the atmosphere. It involves adding alkaline substances, such as basalt or calcium oxide, to ocean water to ...

One solution is to accelerate and enhance the ocean's natural uptake of CO2 by increasing its alkalinity. Ocean Alkalinity Enhancement (OAE) mimics the natural process of rock weathering by adding ...

Adding Lime To Seawater May Cut Carbon Dioxide Levels Back To Pre-industrial Levels Date: July 22, 2008 Source: Society of Chemical Industry Summary: A workable way of reducing carbon dioxide ...
