Using castor oil to separate microplastics from four different environmental matrices
AI summary Read the abstract
This study developed a low-cost, low-risk method for separating microplastics from soil, sediment, water, and biota samples using castor oil as a density separation medium. The approach offers a more affordable and accessible alternative to commonly used high-density salt or zinc chloride solutions for environmental microplastic extraction.
An affordable, low-risk and quick method for the separation of microplastics from four environmental matrices based on castor oil.
