Removal of bacteria by adsorbents prepared from moroccan oil shale

چکیده
In this communication, we present the results of a study on the process optimization for the development of adsorbents from oil shale Moroccan of Timahdit layer (Y) and their application to the elimination of certain types of bacteria contained in the domestic liquid wastes. The adsorbents prepared thermally are characterized by different physico-chemical techniques and their performance adsorption is evaluated by determination of the maximum adsorption capacity of methylene blue. Bacteriological tests were performed on bacteria, Escherichia coli type, contained in domestic liquid wastes. The characterization results showed that the adsorbent obtained by thermal activation of the decarbonated raw rock temperature equal to 300 °C for 2.5 hours in air has good textural and structural properties. In addition, the tests of elimination of bacteria (Escherichia-coli) are conclusive, and allow providing a broad use of these adsorbent in this type of application.

Carbon/Attapulgite Composites as Recycled Palm Oil-Decoloring and Dye Adsorbents
Activated clay minerals have been widely used in the edible oil refining industry for decolorization of crude oil by adsorption, and so far many methods have been used to improve their decolorization efficiency. Herein, we successfully prepared a series of carbon/attapulgite (C/APT) composite adsorbents by a one-step in-situ carbonization process with natural starch (St) as the carbon source. I...

In the process of crude oil desalination, the aim is to separate dispersed phase of brine from oil phase. The project aim is the use of carbon nano-adsorbent for remov-al of salt from crude oil that, unlike other methods of salt separation from crude oil currently used, is a simple, inexpensive method with good ability to remove salt from crude oil. In this study, first, four types of carbon ad...

A method for treating fuel oil and waste water of power plant is suggested which is including vanadium elimination through contacting with humic acid coated magnetic nano-adsorbent. The nano-adsorbent was modified with humic acid (HA) as a compound having carboxyl, hydroxyl and amin functional groups. HA/Fe3O4 nanoparticles were prepared by a co-precipitation procedure and were character...
