ABSTRACT Activated carbon fibers and modified alginate were prepared by using a cheap precursor material. The adsorption behavior of these materials was studied toward basic dyes. It found that the most effective factor in process onto ACF is high surface area followed little assist carboxylic groups on surface. On contrary, only created (MA) will govern MA. equilibrium time for dyes to be 37 min, whereas MA it 70 min. difference rate between attributed their structure features. Langmuir...
In this study, the adsorption of three different blue anthraquinone dye classes (Reactive, Acid and Disperse dyes) were investigated using activated carbon fibre prepared from polyacrylonitrile (PAN) waste. The use based fiber (PAN-ACF) for these dyes has been examined exhaustion method at operational conditions such as concentration temperature. It was found that dyestuffs on PAN-ACF increased with increasing addition, ACFs exhibited higher capacities non-ionic disperse than those anionic...
The development of the changes structure during thermal treatment polyester fiber is studied. Critical dissolution time (CDT) was evaluated to trace in crystallinity and crystal morphology fibers. CDT increased as increased. change less effective for samples thermally treated at temperatures up 160°C, which may indicate a nucleation tendency tiny crystals. 200°C air found be relatively high, while silicon oil medium can affect both amorphous crystalline regions, increasing disorder. effect...
In this study, the adsorption characteristics and performance of activated carbon fibers (ACF) were prepared from Polyacrylonitrile (PAN) waste, for removal heavy metals was investigated. The effects concentration, temperature, pH solution contact time iron sulfate lead acetate studied to determine best properties. surface ACF before after process investigated by scanning electron microscopy (SEM) Energy Dispersive X-ray Spectroscopy (EDX). mainly affected media temperature. 4.0 optimum one...
A CTIVATED carbon fiber (ACF) is considered a superior absorbent material due to its numerous advantages such as, high surface area, several pore volumes and distinct chemistry.ACF has the ability remove organic inorganic compounds from waste materials.The present work aims prepare activated polyacrylonitrile fibers evaluate Co(II) water as well microbes.The results revealed that, maximum adsorption of onto ACF was 92.9 % at pH 10 30 •C.The sorption capacity increased with increasing...
Agricultural industries are considered one of the important in countries with agricultural resources, where these balance supply and demand for crops, that is done through surplus production fresh consumption, addition to providing preserved products throughout year.The research problem although food manufacturing Egypt has many features, such as availability raw materials labor, but loss now most problems facing Egyptian vegetable fruit lack intertwined relations between producers...
