One of the main factors of an aggregate hydroponic system is to use a suitable plant media with local origin. Thus the objective of this research was to study the possibility of replacement of cocopeat as an imported material with local materials and the effects of such media on the growth and flowering characteristics of Rosa hybrida cv. Maroussia. A randomized complete blocks design experimen...
Nowdays, iron nanoparticles due to their unique characteristics are used in all of sciences and technology. These nano particles due to their electrical, magnetic, optical and catalytic properties and having high area and activity that is promped by their small size and most importantly many scientists from the entire world are interested in their low cost production. In this project we used me...
In order to investigate the effect of zeolite on growth indices, yield and grain yield components and protein of lentil in dryland and supplementary irrigation conditions, a field study was conducted in Shahrekord University, Shahrekord, Iran. The experiment was performed as a split plot in a randomized complete block design with three replications. The main factor included three levels of irri...
in order to evaluate the effect of zeolite application and selenium spraying on some physiological traits and grain yield in medicinal pumpkin (cucurbita pepo l.) under different moisture regimes, a study was conducted in a factorial experiment based on randomized complete block design with three replications during 2010 in takestan at gazvin province, iran. the three levels of irrigation facto...
Background: There are great resources of natural zeolite in Iran. Zeolite, an inorganic ion-exchanger, may be used as a suitable technical-economical solution for water treatment in many regions of Iran. In this study, the characterization of natural zeolite natrolite and the feasibility of removing hardness, cations, and anions were investigated. Methods: First, zeolite composition and type we...
Zeolite nanoparticles with various organosilanized surfaces have been synthesized in situ by a one-step approach which provides not only a functionalized surface for diverse host-guest interactions but also an attractive path for preparation of monodispersed template-free zeolite nanoparticles.
aims: arsenic contamination of natural water resources has become an important environmental problem in the world. the adsorption method by iron filings adsorbent or zero-valent iron was used. the study aimed to evaluate the efficiency of iron filings in arsenite removal from polluted water and to investigate the effect of magnetic field on the process. materials & methods: this interventional ...
Background and Objective: The presence of natural organic materials (NOM) in water resources affects its quality (i.e. color, odor, and taste). In addition, it leads to the fouling of filters and membranes and reduces water treatment efficiency during flocculation/ coagulation. Moreover, NOM reacts with disinfectants and produces byproducts (DBPs), which are harmful to human health. Magnetic na...
Background and purpose: Nitrobenzene (NB) as the main material of synthetic fuels, cleaners, rubber and explosives is discharged into the environment and groundwater in large-scale. This compound is considered as a persistent organic pollutant with high toxicity and stable chemical structure which can cause serious risks for human health and ecosystem even in low concentrations. Therefore, the ...
Magnetic zeolite/iron oxide nanocomposite was prepared by mixing zeolite synthesized from coal fly ashes with magnetite nanoparticles in suspension and was used for the removal of Reactive Orange 16 (RO16) and Indigo Carmine (IC) from aqueous solutions. The effect of various experimental parameters such as contact time, pH, adsorbent dose and temperature were investigated. The experimental data...
