Those organic pigments and dyes including a certain amount of toxic materials, heavy metal ions, organic pollutants and deep color flow into natural streams and rivers to cause serious pollution [1].
As well as saving sorbent materials, we reduce expense.
With rapid development of science and technology, nano-Fe3O4 particles will be widely used as ideal sorbent for dye wastewater.

This means that they are renewable materials, which are biodegradable and therefore can be easily recycled.
These problems can be avoided by using pulp or paper fibers for reinforcing thermoplastic matrix materials.
Materials and Methods All composites were fabricated with polypropylene (PP) HD 120 MO as a matrix polymer.
