The purpose of this research is to investigate the effect potassium fertilization source and dose on productivity quality parameters strawberry. trial was conducted in 2016-2017 at experimental greenhouse Hassan II Institute Agronomy Veterinary Sciences Rabat. Strawberry plants cultivar “San Andreas” were planted November 6th 12 liter pots equipped with a gravity fertigation system. design spli...

Different chemical formulations for the synthesis of highly intercalated graphite bisulfate have been tested. In particular, nitric acid, potassium nitrate, potassium dichromate, potassium permanganate, sodium periodate, sodium chlorate, and hydrogen peroxide have been used in this synthesis scheme as the auxiliary reagent (oxidizing agent). In order to evaluate the presence of delamination, an...

Alkali pretreatment is one of the chemical technologies that has been examined on various types lignocellulosic biomass. To gain a better insight into effects potassium-based catalyst pyrolysis behavior with different materials, potassium bicarbonate (KHCO3) and nitrate (KNO3) were used as additives in this study. The experimental parameters which included particle size, heating rate, additive ...

using uv-vis spectrophotometric method, the formation constant for interaction of fe2+(aq) ion with l-alaninewas experimentally studied at ph = 4.1 ± 0.01 (50mm of potassium hydrogen phthalate buffer), ionic strengthof 0.1m potassium nitrate and at 5 different temperatures 15,20, 25,30 and 35 t. the optical absorption spectraof mixtures containing considered cation and l-alanine were analyzed b...
