Nanocomposites made from jackfruit peel can reduce water pollution

Wastewater contains nutrients such as nitrogen and phosphorus, which are needed by plants to grow. Fertilizer wastes flow from the fields to water bodies like rivers and ponds, and act as nutrients for the plant group found there.

These nutrients are often known to encourage unwanted plant growth, such as algae, on the surface of water bodies. This hinders the process of photosynthesis of phytoplankton beneath the surface of the water. In addition, some algae also emit toxic substances. Dead algae decomposed by bacteria deteriorate the quality of the water, causing a foul smell. some bacteria; They also produce methane, which is a greenhouse gas.

Indian researchers have found an eco-friendly way to tackle this problem. They have developed nano-composites based on jackfruit peel. They say these nano-composites could be helpful in separating nutrients such as nitrogen and phosphorus from wastewater. This study has been done by researchers from Graphic Era University, Dehradun.

To prepare the nano-composite, they have heated dried jackfruit peel and powdered it. The researchers argue that the nano-composite, made from polysaccharide-containing jackfruit peel powder, has the higher pore diameter and surface area required for improved adsorption capacity. They extracted polysaccharides from mushrooms and applied them magnetically to jackfruit peel powder.

When tested, the nano-composite showed maximum nutrient removal efficiency at pH-4 to pH-6. In this situation, in laboratory tests, the researchers found that these nano-composites could remove 99% of phosphates and nitrates from water. The researchers then tested the nano-composite in a continuously flowing wastewater system. It removed up to 96% of phosphates and nitrates from wastewater.

Researcher Brij Bhushan from Graphic Era University, Dehradun says that “Nano-composites based on jackfruit peel have demonstrated their ability to remove phosphates and nitrates from waste water even in the presence of selective ions.”

Her colleague Arunima Nayak says, “Even after six cycles of reuse, the nano-composite showed only a 10 percent reduction in nutrient removal capacity. This means that it is possible to reuse this composite. Environmentally friendly nano-composites are an inexpensive way to separate nutrients from the water, which could reduce water pollution.
