The objective of this work is to determine changes of surface properties of a bentonite after acid activation, using hydrochloric acid solutions (HCl) at room temperature. XRD, FX, FTIR, MEB, and BET analyses of the samples have been carried out to examine the structure of bentonite before and after acid activation. It is found that the raw bentonite is composed of dioctahedral montmorillonite ...

The XRD powder-patterns for some representative bentonites, natural and acid-activated, are given in Fig. 1.The bentonite investigated displays peaks belonging to the clay mineral smectite (with a d 0 0 1 value of 1.49 nm), and non-clay minerals, quartz, opal, and feldspar. Characteristic XRD peaks were identified according to the literature (Moore & Reynolds, 1997).

REACTIVITY OF CLAY MINERALS WITH ACIDS AND ALKALIES*

Acid activation caused an increase in moisture content to occur from 14.2% in raw clay to 17.4% in 3 M HCl activated clay, representing an increase of 3.2%. The moisture content for the clay lies within 10–18% recommended by Wiedermann [ 5 ] as being appropriate to ensure that the clay structure does not buckle and loses its adsorptive capacity.

Apr 14, 2020· From the abovementioned results, it is concluded that the optimum operating conditions for the synthesis of bentonite coated by nano graphene oxide layer using sugar fine powder as source of carbon were bentonite substrate 1 kg, sulfuric acid concentration 1.5 kg/kg clay, sugar fine powder 50 g/kg clay, water 3000 ml/kg clay, and stirring time ...

Characterization, Acid Activation, and Bleaching ...

Clay E is a swelling bentonite (Clay Spur) of the western type and, as is typical, changes relatively little upon acid activation. As is obvious, surface area can be made to improve quite dramatically for the non-swelling bentonltes, but in all cases it does pass through a maximum beyond which additional acid treatment actually reduces surface ...
