The novel lanthanum-modified clay water treatment technology (Phoslock seems very promising in remediation of eutrophied waters. Phoslock is highly efficient in stripping dissolved phosphorous from the water column and in intercepting phosphorous released from the sediments. The active phosphorous-sorbent in Phoslock is the Rare Earth Element lanthanum. A leachate experiment revealed that lanth...

Conventional resources of phosphorous are at high risk of depletion in the near future due to current practices of its exploitation, thus new and improved exploration methodologies need to be developed to ensure phosphorous security. Today, some treatment plants recover phosphorous from municipal wastewater as struvite (MgNH₄PO₄·6H₂O). Magnesium is often added to the wastewater as MgCl₂·6H₂O to...

abstract the increasing of yield per unit area is usually achievable by improving the soil fertility level through using (chemical) fertilizers. the purpose of the present research was to evaluate the 6 extraction methods including olsen, morgan, ammonium bicarbonate-dtpa, colwel, bray and mehlich 3 in order to specify a suitable extractant(s) for estimating available phosphorus through using 2...

Higher serum phosphorous is associated with cerebral small vessel disease, an important driver of cognitive decline and dementia. Whether serum phosphorous, a potentially modifiable parameter, associates with risk of incident dementia is not known. We aimed to examine the association between serum phosphorous and risk of incident dementia and to determine if the association is modified by age. ...

A pot experiment was conducted under greenhouse conditions to study the effect of phosphorus fertilization soil moisture content on some growth indicators, yield and seed nitrogen phosphorous for two wheat cultivars, Adnaniah Sham-6, in calcareous suffering from a lack available phosphorus. The results indicated that led an improvement plant growth, as it caused increase relative water leaves, ...

This work investigates the effects of oxygen and humidity on black phosphorous (BP) arsenic (AsxP1−x ) flakes using Raman spectroscopy in situ electric transport measurements (four-probe resistance thermoelectric power, TEP). The results show that incorporation into lattice BP renders it more stable, with degradation times for BP, As0.2P0.8, As0.4P0.6 being 4, 5, 11 days, respectively. P-P peak...

introduction land use change and its effects on soils is one of the important factors that decrease soil quality. nowadays because of rapid growth of population, vast forest areas are changed into agricultural lands but chemical properties of the soils are commonly affected by changes in land usage.  converting the forest areas into agricultural lands is one of the prevalent issues in iran, esp...
