Synchronous treatment of heavy metal ions and nitrate by nanoscale zero-valent iron (Fe0)(纳米级Fe0同步处理重金属离子与硝酸根的研究)

Zhejiang Daxue xuebao. Lixue ban, 2008
纳米级零价铁(Fe0)同步处理Cu2+、Ni2+、Cr(VI)等重金属离子和硝酸根的实验中发现，硝酸盐对重金属离子的去除基本无影响，而不同重金属离子则对硝酸盐的去除有不同的影响.同步去除Cu2+和NO3-、Ni2+和NO3-时,与单独去除NO3-相比，Cu2+、Ni2+可以明显地提高硝酸盐的去除率和反应速度，并且Cu2+、Ni2+的初始浓度越高，NO3-的去除效果越好，反应速率常数kobs也越大.纳米级Fe0同步去除Cr(VI)和NO3-时，Cr(VI)阻碍了Fe0还原脱除硝酸盐反应的发生，当Cu2 ...

The effect of foliar application of urea, Mo and BA on nitrate metabolism in lettuce leaves in the spring and summer-autumn seasons

Folia Horticulturae, 2011
‘Melodion’ butter lettuce was grown on rockwool slabs in a film tunnel in the spring and summer-autumn seasons. The following experimental factors were investigated: foliar application with a solution of urea (1%), Mo (1 mg dm-3) and benzyladenine (5 mg ...

Effect of Si, Co, Fe contents and cooling condition on the microstructure of Al–Si–Co(–Fe) alloys

Materials Research Express, 2023
In this paper, several Al–Si–Co and Al–Si–Co–Fe alloys were prepared by varying the contents of Si, Co and Fe, solidified via fast and slow–cooling conditions.

NdO(NO3)

Acta Crystallographica Section E, 2008
The title compound, neodymium(III) oxide nitrate, which is isostructural with LaO(NO3), arose from a solvothermal reaction. The Nd ion (site symmetry m) is ten-coordinated by eight O atoms of NO3 groups and two μ2-oxide ions.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...
