Enrichment of Tropical Peat with Micronutrients for Agricultural Applications: Evaluation of Adsorption and Desorption Processes
O objetivo deste trabalho foi avaliar os processos de adsorção e dessorção de micronutrientes em amostras de turfas tropicais visando uma possível aplicação em solos. Para isso, experimentos de adsorção foram estudados em diferentes valores de pH e a partir de solução metálica multielementar e elementar. As capacidades de adsorção máximas ocorreram em pH 6,0 e a ordem de afinidade observada em ...
متن کاملInhibitory effect of fulvic acid extracted from Canadian sphagnum peat on chemical mediator release by RBL-2H3 and KU812 cells.
Fulvic acid (FA) was extracted and purified from Canadian Sphagnum peat (CP-FA) and characterized by using an element analysis meter, Fourier transform infrared (FT-IR) spectroscopy, electron spin resonance (ESR) spectroscopy, and (13)C-nuclear magnetic resonance ((13)C-NMR) spectroscopy. To investigate the antiallergic effect of CP-FA, we incubated rat basophilic leukemia (RBL-2H3) cells with ...

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولadsorption of zn (ii) from aqueous solution by using chitin extracted from shrimp shells
background chitin and its derivatives (chitosan) are natural biopolymer produced from crustacean shell, which due to their active functional groups such as amine and hydroxyl have high ability to absorb heavy metals from water and wastewater. the aim of this study was to investigate zinc removal from aqueous solutions by using chitin extracted from shrimp shells. material and methods to study t...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
