Chinese researchers have developed a new material that can absorb heavy metal ions from fertilizer, decreasing environmental pollution. The material, a nanocomposite, was developed by a team led by Wu Zhengyan of the Hefei Institute of Physical Science under the Chinese Academy of Sciences. It can “grab” arsenic and copper ions from manure with high efficiency…Full Article: Xinhua Sept 2017

Key Point

  • Published in the Journal of Agriculture and Food Chemistry, the new nanocomposite material will reportedly help absorb arsenic and copper which can find its way into organic fertilizer via tainted animal feed.

ChinaAg Comment

  • In September 2017, in addition to the new nanocomposite material that can absorb heavy metal ions, CAS’s Hefei Institute of Physical Science also developed a new “smart” nano-pesticide composed of diatomite, iron magnesium oxide and chitosan. Publicized in the Chemical Engineering Journal, the new pesticide will reportedly only need one spray application on single-season crops. Conventional pesticides typically need multiple spray applications.
