Scientists from The Chinese University of Hong Kong used our 3.5 kDa dialysis tubing in their paper in the February 2017 issue of the Journal of Hazardous Materials. In the article, titled “Removal of harmful alga, Chattonella marina, by recyclable natural magnetic sphalerite”, the researchers used the dialysis tubing to separate C. marina (algae) cells from natural magnetic sphalerite.

Using the dialysis tubing allowed the NMS particles to be washed and reused to continue clearing the harmful algal cells. The process developed in the paper for clearing harmful algal cells has little to low environmental impact and is a low-cost alternative to current solutions.

Abstract: Fish-killing harmful algal blooms (HABs) of Chattonella marina causes serious hazards and risks to fish farming and environment throughout the world. At present, it is necessary to explore cost-effective and recyclable materials for controlling C. marina blooms to reduce the cost and control the potential side effect to the environment. A novel earth-abundant natural magnetic sphalerite (NMS) for removing C. marina was systematically investigated. Click here to read the article.
