This water purification technology is second to none: it removes 99.9% of microplastics in 10 seconds.

they lurk around every corner and are a growing environmental problem, While science steps on the accelerator to find out how they impact animal and human health, Microplastics multiply their presenceReaching the highest peaks, the deepest trenches and the most remote places on the planet, such as faraway Antarctica or the North Pole.

Inside the human body, these microscopic particles have been found in the blood, in the deepest part of the lungs, in the umbilical cord of unborn babies, in the intestines, and even in breast milk. They are also in the water we drink, especially bottled water. Also rain around the world contains “perpetual chemicals” that cause cancer.

Given the dimension of the problem, it is imperative to seek solutions such as: Korean researchers have developed a new water purification system Which can filter out these small pieces and other contaminants with great speed and efficiency.

published in the magazine advanced MaterialsSouth Korea’s Daegu Gyeongbuk Institute of Science and Technology (DGIST) has detailed the promising design. Microplastic filtration technology.

the key lies in a Material known as Covalent Triazine Framework (CTF), which has shown high effectiveness in the removal of organic dyes from industrial wastewater. It has a large surface area and is very porous, so it has a large space inside it to hold molecules.

Scientist Carefully engineered CTF molecules to attract more water and expose the material to mild oxidation, Resulting filter enabled Removes over 99.9% of contaminants removed in 10 seconds. Furthermore, the material can be reused multiple times without reducing its luxurious performance.

In another experiment done, The researchers developed another version of the polymer that is able to absorb sunlight, convert the energy into heat and use it to purify other pollutants.Volatile Organic Compounds (VOCs).

In this second case, the filter was able to remove more than 98% of VOCs with the power of solar radiation. they also made one Prototype that combines both types of membranes, a nearly perfect technology capable of removing more than 99.9% of both types of pollutants from waterVOC contaminants and phenolic microplastics, all at ultra-high speeds.

“We hope this will be a cost-effective universal technology that can purify polluted water and provide drinking water even in areas without electricity,” explains Park Chi-young, lead author of the study.

now-a-days Various materials are being tested to help filter out microplasticssuch as magnetic nanopillars, nanocellulose, semiconductor wires, and filtration columns with sand, gravel, and biofilms. We have to see which of these options takes the lead in the war against these invisible enemies.
