“…The properties of clay that are of interest to the ceramic industry are: its plasticity which facilitates shaping of bodies, chemistry, mineral composition, thermal properties, colour, and mechanical strength after firing [2][3][4]. In Cameroon, burn clays have been used as construction material for colonial buildings as Foumban, Bamunka and Bafut kingdom palaces, and a great interest of clay base materials is noticed since a decade, with development of fire bricks factories and art craft manufacturing.…”

a b s t r a c tThe physicochemical, mineralogical and technological properties of clayey materials from the Ndop plain (NW Cameroon) have been investigated, for their ceramic applications. The clayey materials have mixed facies with colour ranging from brown, grey, mottled and yellowish brown. The thickness of the exploitable clay layer is more than 5 m. Their mineralogical constituents are quartz, kaolinite, illite and feldspars, with kaolinite as major clay mineral. Based on the geochemistry, their source rocks might be felsic, with a mafic rock inference. These materials display high percentage in fine particles and high Atterberg limits. For all the firing temperatures, flexural strength (1.2-11 MPa), water absorption (8.03-24.27%), linear shrinkage (2.10%), weight loss (4.88-16.54%) and bulk density (1.57-2.03 g/cm 3 ) indicate good ceramic properties for firing samples between 900 and 1100 • C. Most of the fired test bricks show a brick red colour with good to very good cohesion. The studied clays were thus, suitable as raw materials for roof tiles, light weight blocks and hollow bricks; however, mixing of high clayey and highly silty materials could improve the quality of the products.

“…Clays are widely applied in many fields such as polymer nano-composites [1][2][3], adsorbents for heavy metal ions [4,5], catalysts [6,7], photochemical reaction fields [8], ceramics [9], paper filling and coating [10], sensors and biosensors [11], due to their high specific surface area, chemical and mechanical stabilities, and a variety of surface and structural properties [12,13].…”

“…Naturally occurring clay minerals offer a great potential and are widely applied in many fields, e.g. polymer nano-composites (Fischer 2003;Sinha Ray & Okamoto 2003;Zeng et al 2005), heavy metal ion adsorbents (Bradl 2004), catalysts (Gil et al 2000;De Stefanis & Toklinson 2006), paper filling (Bundy & Ishley 1991), ceramics (Burst 1991), and sensors (Mousty 2004), because of their high specific surface area, high mechanical stability, and three-dimensional structure. The clays most often used as nano-adsorbents are montmorillonite/smectite group and kaolinite group clays.…”

Malachite green (MG) has an extensive use as a biocide in aquaculture industries throughout the world. It is found to be highly effective against protozoal and fungal infections, besides being used as colorant for textiles and coloring additives in packed foods and fish industries. Aquaculture industries have used MG for topical applications by bath or flush methods, without giving due attention to the fact that in topical application, the therapeutants might be absorbed systemically and may produce significant internal effects. The presence of nitrogen in the ring structure of MG makes it a very controversial compound as it poses risks to those who consume MG-exposed fishes; it also causes subsequent detrimental effects to the immune system by genotoxicity and carcinogenesis. Another concern arises due to progressive accumulation of leucomalachite green formed via biotransformation of MG in various tissues; it can enter mammalian cells through the food chain and poses high toxicity. Diverse treatment strategies such as oxidation, filtration, photo degradation and photo catalytic degradation are available for MG removal. These methods do not degrade the pollutants or contaminants effectively and are time consuming as well as costly. Compared to these techniques, adsorption has now been proved to be a highly efficient and cost-effective method to remove this toxic dye from wastewater before it is released into the aquatic environment. This study has attempted a compilation of various adsorption matrices and their feasibility for MG removal.
