Removal of harmful dyes and colours from water bodies

Dyes are extensively used in leather, textile, paper, and plastic industry

Globally around 7,00,000 metric tones of dye are generated each year.
Most of the industries discharge dye effluent without proper treatment into waste stream often leading to the river, lakes, and ponds. Dyes contaminate water disrupting the aquatic ecosystem. Dyes block sunlight and prevent plant photosynthesis.

A COLORED RIVER

A group from Washington University has made a domain agreeable strategy to expel shading from colors in water inside a couple of moments. The technique named 'Applied Catalysis B: Environmental' was published online in june.

The research team developed a sponge-like material made from wood pulp and bits of metal. Cellulose is the main backbone behind this material consisting of tiny bits of palladium. The metal acts as a catalyst removing the color quickly. The process would have taken weeks if not palladium catalyst was used which drives the reaction almost instantaneously.

The research team combined cellulose with palladium, heated the mixture and mixed in a blender. Then they purified and freeze-dried the material. A porous was formed consisting of 99% air. Much the same as a genuine wipe this material could be pressed and reused various circumstances without losing its capacity to expel shading.
