The Rengen Grassland Experiment: soil contamination by trace elements after 65 years of Ca,N, P and K fertiliser application

The Rengen Grassland Experiment (RGE) was established in the Eifel Mts. (Germany) on a low productive Nardetum in 1941. Since then, the following fertiliser treatments have been applied along with a two cut system: unfertilised control, Ca, CaN, CaNP, CaNP–KCl and CaNP–K₂SO₄ with basic slag (syn. Thomas phosphate) as the only P fertiliser. The effect of long-term fertilisation on plant-available (extracted with 0.01 mol l⁻¹ CaCl₂), easily-mobilisable (extracted with 0.05 mol l⁻¹ EDTA), potentially-mobilisable (extracted with 2 mol l⁻¹ HNO₃) and total concentrations of trace elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the top 0–10 and 10–20 cm of soil were investigated in 2006. According to redundancy analysis (RDA), the effect of treatment on the concentrations of risk elements was significant and explained 82.3 and 90.6% of the variability in the data in the 0–10 and 10–20 cm soil layers, respectively. Basic slag supplied the soil with considerable amounts of As, Cr, Cu, Fe, Mn and Zn. Following 65 years of fertiliser application the concentrations of risk elements in the soil profile had increased substantially, especially with basic slag. However, threshold limits for total trace element concentration in soil permitted by Czech national legislation were exceeded only in the case of As. The increase in plant-available As concentrations was most critical as it increased the potential uptake of As by plants in plots fertilised with P. Although P treatments received more than 300 g of Cr ha⁻¹ annually, no effect on plant-available Cr soil content was detected. This contrasted with the accumulation of total Cr in the 0–10 and 10–20 cm soil layers. Furthermore, plant availability of Cd, Fe, Mn and Zn was affected by soil pH and generally decreased with the application of quick lime. Plant availability of these elements was not correlated with amounts supplied by fertilisers.

水玻璃激发矿渣制备纳米地质聚合物研究

采用扫描电镜(SEM)、结合能量散射X-射线能谱分析(EDXA)、场发射扫描电镜(FESEM),对水玻璃激发矿渣细粉水化产物的生成及发展进程中的微观形貌进行了系统的研究.在水化早期,矿渣玻璃体快速解体,形成大量的硅溶胶和铝溶胶覆盖于矿渣表面;随着龄期的延长,硅铝溶胶之间发生缩聚反应,生成相互搭接的树枝状网络结构的地质聚合物凝胶体,表明矿渣玻璃体的解体是一个形成溶胶的过程.而缩聚反应是一个形成凝胶的胶凝过程.纳米地质聚合物结构密实,抗压强度从1d的26.5MPa增至28d的60.IMPa.地质聚合物是由20nm左右的颗粒搭建成的网络结构所组成.

Electrowinning of iron from sulphate solutions

During a 10 years period from 1947 to 1957, a research group at the smelter owned by Orkla Grube-Aktiebolag at Thamshavn, Norway, developed the so-called Pyror Process, the aim of which was to take care of all the valuable components in the copper-bearing pyrite ore being produced at the nearby Lökken mine. The present paper describes pilot plant operation of the crucial step of this process, which is electrowinning of iron from a sulphuric acid solution, using iron starting sheets and lead anodes surrounded by a diaphragm. High purity iron was produced, with a current yield of 85% and a power consumption of 4.25 kWh/kg iron.
