Scientists made a cool new tool to clean up heavy metals from water. They used tiny plants called diatoms, mixed them with some special stuff, and created a super material. This material can grab onto metals like cadmium, copper, and lead. The team tested this new material in different conditions.
Adsorption is a big deal in water cleanup. It's like a magnet that pulls out nasty stuff from water. But, it's not as simple as it sounds. There are three big things that make it work: how much stuff can stick to a surface, how much stuff is left in the water, and how the stuff sticking to the surfa
Nanoparticles, tiny pollutants, are a big worry. They can harm nature and people over time. A recent study looked at how these nanoparticles stick to and come off of aerobic granular sludge (AGS) in wastewater treatment. AGS is a special kind of sludge used to clean water. The study found that the
Wheat straw, often seen as farm waste, has a new role in cleaning up water. Scientists have found a way to tweak it chemically to soak up a harmful dye called Rhodamine B. This dye is tough to break down and can be toxic. The modified straw, now called EWS, is a game-changer. EWS is made by treatin
Rubidium is a valuable element found in salt-lake brines, but extracting it has been a tough job. The usual methods aren't great at picking out rubidium from other stuff like sodium, potassium, calcium, and magnesium. But now, there's a new trick: using a special material with lots of sulfonic acid
Sunflower straw, a common agricultural waste, has been given a new purpose. Scientists have been experimenting with it to clean up oil spills. They treated the straw with two different chemicals: silanization and acetylation. The goal was to see how well the treated straw could soak up oil. The exp
Nickel catalysts are not as good as their noble metal counterparts for hydrogen oxidation in alkaline environments. They only have 1-2% of their activity. This is a problem because scientists don't fully understand why. But recent research sheds some light on this issue. The study looked at how dif
In seriously ill patients, the way the body processes medicine can change. This is especially true for a drug called caspofungin. Doctors use a special machine called continuous renal replacement therapy (CRRT) to help these patients. The machine has filters made from a material called polyacrylonit
The challenge of capturing carbon dioxide from industrial exhaust gases is real. The main issue is humidity. Most materials used to trap CO2 are porous. They have tiny holes that can soak up water more easily than CO2. This is a problem. Water can crowd out CO2, making it harder to capture. It also
Zeolites are like superheroes in the chemical world. They are used to separate and process things in both gas and liquid forms. They are known for their special abilities: they can pick out specific molecules, soak up lots of stuff, be reused, and stay stable. One type of zeolite, called H-MFI, has
