Why in the News?<\/h2>\n

Researchers at the Indian Institute of Science (IISc) have developed a sustainable hydrogel<\/span> specifically designed to tackle the menace of microplastics in water.<\/p>\n

1) The hydrogel utilizes a complex interpenetrating polymer network (IPN) architecture<\/span> composed of chitosan, polyvinyl alcohol, and polyaniline.<\/span><\/p>\n

2) This structure is infused with nanoclusters of copper substitute polyoxometalate (Cu-POM),<\/span> which act as catalysts under UV light irradiation to degrade microplastics. <\/span><\/p>\n

3) The synergistic effect of the polymers intertwined with the catalytic nanoclusters enhances the hydrogel’s stability across various temperatures<\/span> and also enables it to adsorb and degrade large quantities of microplastics efficiently. <\/span><\/p>\n

4) This hydrogel efficiently removes about 95% and 93% of two different types of microplastics in water,<\/span> highlighting its potential as a significant solution in water purification technologies.<\/p>\n

5) The hydrogel could last for up to five cycles of\u00a0microplastic\u00a0removal<\/span> without significant loss of efficacy.<\/p>\n

6) This hydrogel can also be converted into carbon nanomaterials<\/span> that are capable of extracting heavy metals, such as hexavalent chromium, from contaminated water.<\/p>\n

About Microplastic<\/h2>\n

1. Microplastics are small plastic particles<\/span> in the environment that are generally smaller than 1 mm to the 1 micrometer range.<\/span> Microplastics can be formed by fragmentation of large plastic waste material.\u00a0<\/span><\/p>\n

2. Danger of Microplastics to humanity and overall biodiversity:<\/strong><\/p>\n

a) Microplastics pass the filtration and treatment processes for wastewater<\/span> resulting in significant global impacts on wildlife from marine environment pollution.<\/p>\n

b) Microplastics kill biodiversity and other organisms’ fish<\/span> before they reach reproductive age. It lead to stunted growth and behaviour change in some organisms.<\/p>\n

c) Large amounts of plastic are not recycled and end up in landfills<\/span>, posing a threat to human health.<\/p>\n

d) The durable properties of plastics make them persistent and slow to degrade in the environment entering the food chains<\/span>. It holds the potential for both bioaccumulation and biomagnification.<\/p>\n
