New technology overweight soil heavy metal governance poplar actually become the key

At present, the situation of soil heavy metal pollution in our country is more and more severe. Pops of flying trees can even break the bottleneck of governance. It is said that in the near future, researchers from Science Island have found new existent value for Poplar - adsorbent for heavy metals and organic pollutants in water! The adsorbent has the advantages of high efficiency and economy, and has certain value and significance in sewage treatment.

At the turn of the spring and summer, the flying bursts of poplar make people hate the itch, seemingly useless poplar is actually a malleable talent in the hands of Science Island researchers, it can absorb heavy metals in the water; and for the soil Heavy metals, scientists also have a way for efficient removal. Recently, the reporter learned from the Science Island, researchers with sucrose and other composite materials to remove highly effective soil heavy metals, but also to Xu Yang turning waste into treasure yet.

Heavy metals in soil can be efficiently removed

Soil heavy metal pollution will lead to excessive levels of grain heavy metals, a serious threat to human health, China's agriculture is the key issues to be solved.

Existing soil heavy metal management is usually replaced by soil replacement, phytoremediation, chemical passivation and other methods, not only complicated operation, low efficiency, and difficult to quickly remove heavy metals from the soil, greatly limiting its large-scale applications, the urgent need to develop a Convenient and efficient soil heavy metal removal method.

Recently, the research group of Wuzheng Yan, a researcher at Science Island Institute of Technology and Biology, using magnetic ceramsite as a carrier, made a kind of functional magnetic nanocomposites by using natural materials such as sucrose, which can efficiently capture hexavalent chromium in soil and convert it into micro Toxic trivalent chromium, but also through independent research and development of magnetic separation system to remove chromium from the soil efficiently, thus fundamentally solve the problem of soil pollution of heavy metals. The method is environment-friendly, easy to use and recyclable, breaking through the key bottlenecks in the field of soil heavy metal pollution control and providing a new approach for soil heavy metal treatment with good application prospects.

Poplar become "plastic talent"

Speaking of Yang Xu, most people will hate tooth itch it. Whenever the spring and summer, popsicles flying in the sky will give people a great deal of trouble: Yang Xu inhaled the body will stimulate the respiratory tract caused by severe coughing, sneezing, runny nose and other allergic phenomena. In addition, poplar fibers are organic fibers, flammable, but also very easy to cause a fire. However, in the near future, researchers from Science Island have found new existent value for Poplar - adsorbents for heavy metals and organic pollutants in water! Poplar is actually "plastic talent"!

We know that polycyclic aromatic hydrocarbons, antibiotics and organic compounds such as dyes and inorganic heavy metal ions are one of the important factors that cause water pollution. Therefore, it is very important to find an efficient and economical adsorbent.

Plasma Li Jiaxing task group turned waste into treasure, to Xu Xu as a raw material to prepare an adsorbent, inorganic heavy metal ions and organic pollutants (methyl blue, methyl orange, Congo red, chloramphenicol and naphthol) Have good adsorption properties. The adsorbent has the advantages of high efficiency and economy, and has certain value and significance in sewage treatment.
