In water and wastewater, phosphate anions are considered critical contaminants because they cause algae blooms eutrophication. The present work aims at studying the removal of from aqueous solutions using silica particles functionalized with polyethylenimine. parameters affecting adsorption process such as pH, initial concentration, adsorbent dose, presence competitive anions, carbonate, nitrat...

The association of osteomalacia with neurofibromatosis is a very rare entity. Here a 34 year old man, a known case of neurofibromatosis, is reported who presented with bone pain, hypophosphatemia, rena] phosphorus wasting, multiple Looser's pseudofractures, and low bone density. Treatment with high dose calcitriol and phosphate resulted in temporary treatment. Permanent cure was achieved a...

The addition of phosphorus as phosphate ion is one of the most serious environmental problems because of its contribution to the increased eutrophication process of lakes and other natural waters. Microbial strategies for the removal of environmental pollutants from waste streams or contaminated sites can provide an attractive alternative to traditional methods such as incineration or disposal ...

background: investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. the advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. th...
