Dyes are widely used in industry including textiles cosmetics paper pharmaceuticals and printing [1] Many dyes are toxic and not biodegradable due to their complex chemical structures and the presence of aromatic rings in their structures [2] Therefore it is essential that the dyes are removed from the wastewater before being discharged into the
In contrast activated clay Fig 3b revealed a rugged and uneven surface of the adsorbent providing a large surface area m 2 g −1 and porosity for adsorption The adsorption capacity of the HCl activated bentonite was almost three times higher than that of raw BCs
The activated bentonite absorption band at 3 621 cm −1 shows a free O H group on the surface of the activated bentonite A peak was also observed at 1 626 cm −1 bending and stretching bands Al Al OH which indicates a leaching out of octahedral cations like Al 3 and Mg 2 from the structure of bentonite
Acid activation was carried out by heating muds prepared from Ca rich bentonite CaB sulfuric acid H 2 SO 4 and distilled water yielding various bleaching earths BEs The roles of each of the process variables namely mass fraction of H 2 SO 4 x in the dried CaB and pure H 2 SO 4 mixture heating temperature T and contact time t in the activation were tested
purpose it is important to investigate both raw bentonite RB and acid activated bentonite This study aims to improve the quality of tap water used for wire electrical discharge machining; the study focuses on decreasing the electrical conductivity of tap water using a low cost adsorbent such as RB or acid activated bentonite
In contrast activated clay Fig 3b revealed a rugged and uneven surface of the adsorbent providing a large surface area m 2 g −1 and porosity for adsorption The adsorption capacity of the HCl activated bentonite was almost three times higher than that of raw BCs

Keywords activated bentonite acid activation microwave heating oil soluble green pigment adsorption Introduction As it is known vegetable oils contain many kinds of pigments including
A new process for manufacturing organically compounded bentonite was developed successfully based on the organic intercalation and layered structure of bentonite The main steps in the proposed process included wet sodium activation of bentonite ore organic compounding and high pressure roll grinding The optimum procedure is recommended as
This study aimed to investigate the characteristics of acid activated bentonite by focusing on its capability of improving the quality of tap water used during wire electrical discharge machining Raw bentonite RB was activated using sulfuric acid
Moreno and Peinado [22] sorted bentonite into three categories which are sodium bentonite calcium bentonite and activated sodium calcium bentonite First the natural sodium bentonite has moderate to high swelling index due to a balance population of exchangeable ions between sodium and calcium with pH recorded around 9 Second is the natural
Abysinicus derived activated carbon/bentonite clay/graphene oxide/iron oxide nanocomposite for removal of chromium from aqueous solution Solomon Tibebu 1
In this work simple conditions were applied to modify bentonite for the removal of pesticides from aqueous solution Bentonite was modified in a single step as with HCl M and BC500 calcined at 500 °C and combined steps with different sequences and These adsorbents were characterised by XRD XRF FT IR 27Al MAS NMR
TRANSFORMER OIL WITH ACTIVATED BENTONITE AND ANTIOXIDANTS Ashish Bohra1 Deepak Somani2 Department of Electrical Engineering SS College of Engineering Udaipur Rajasthan India ABSTRACT This work focuses on reclaiming and enhancing critical characteristics of aged mineral oil and fresh transformer oil using activated
Activated bentonites are low cost acid catalysts used in several reactions However their application at an industrial scale is affected by the formation of colloidal suspensions when these bentonites are in aqueous solutions In order to overcome these limitations this work proposes obtaining a catalyst based on a composite containing natural
32 acid activated fuller s earth bentonite clay Treatment with inorganic acid Sulfuric acid and hydrochloric 33 acid activated bentonite clay is very efficient and shows satisfactory results But there is a major disadvantage 34 associated with its use Fumes of hydrochloric acid or sulfuric acid are very dangerous for both the
bentonite using hydrochloric acid HCl solution and measure the metal content of NaCl Pb Ca and Mg using AAS The synthesis of activated bentonite was carried out using the hydrolysis method using M HCl 1 10 Bentonite was separated from the filtrate and dried at 110°C for 2 hours Bentonite which had been activated with HCl

A known weight of the activated Iraqi bentonite was added The flask was heated until its temperature ˚C and was reached 90 maintained at this temperature for 30 minutes The oil was immediately filtered under gravity using Whatman filter paper no 42 15 cm diameter diluted with n hexane then
1 Activated Charcoal Activated charcoal is a fine black powder It s been used as a binder for hundreds of years Some poison control centers still use activated charcoal to help with drug overdoses and the like 2 3 To make activated charcoal manufacturers start
The activated bentonite ABn was further utilized for the removal of Cu II and Pb II ions from aqueous solutions Batch reactor studies showed that the removal of these toxic metal ions was favored by increases in the pH initial metal concentrations contact time and dose of the adsorbents
