Purification of natural clays using physicochemical process. Application for preparation of a new
ultrafiltration membrane for Red 80 removal from aqueous solutions

his paper describes the protocol and the optimization of a
purification procedure of two various types of Moroccan
clay materials: Marl (smectite-rich clay) of Fez smooth (A) and
rough (B).
The purification method was investigated. The impurities
were removed prior to separating fine particles. The chemical
purification was carried out following a precise protocol in
order to eliminate the various impurities (carbonates, iron
oxides and organic matter) without affecting the clay minerals.
Our approach is based on following and control of this several
operations by using a set of analyzes, such as X-Ray Diffraction
and Infra-Red (DRX and IR) and imaging microscopic such
as Scanning Electron Microscope and Transmission Electron
Microscope (MEB or SEMand TEM). As application, the purified
fraction of clay is used as deposit on membrane supports
prepared from raw clay, utilizing a spin-coating technique to
develop the UF membrane. Visual study as well as scanning
electron microscope of the prepared membranes shows that
the deposited layer is homogenous and free of structural
defects. The average pore diameters were determinate to be
approximately 75 nm and 90 nm respectively for M1 and M2.
Finally resulting UF membranes were tested by measuring the
water permeability and the filtration of Red 80 solution.

Hanae Ouaddari obtained her engineering degree from Ecole Mohammedia des
Ingenieurs in 2004 into Industrial Process Engineering (Major). She then joined the
National Center for Scientific and Technical Research as Laboratory Manager for Atomic
Emission Spectrometry. In 2015 she joined the Laboratory of Materials Membranes
and Environment of Faculty of Sciences and Technologies of Mohammedia, University
of Hassan II as PhD student. Since 2018, she has been responsible for the Chemistry
Platform, which includes eight laboratories offering analytical services in the fields of
molecular chemistry and synthetic chemistry. Her current research interest includes
the valorization of Moroccan clays for environmental applications to catalysis,
adsorption and ultrafiltration.
