“…The analysed material is devoid of carbonate components. The loss on ignition of Makabaye clay materials is 3.66%, which confirms the presence of low organic matter, and interstices retaining some water [37][38][39][40][41].…”

“…Kaolinitic clay have an unmodified semi-booster natural gums character; this power is even greater than clay used are pure and well crystallised. Kaolinite content supports the semi-reinforcing grades whereas quartz and mica it unfavorable [35][36][37][38][39][40][41][42].…”

“…The general method involves bombarding the sample with X-rays from a metal anode, and which are first plugged by a divergence slit to produce a sub-parallel beam. This is directed at the sample at the angle θ and is diffracted when the conditions of the Bragg law are fulfilled [39][40][41][42].…”

This scientific work was initiated as a result of many concerns facing most researchers on the nature, properties and characteristics of the clay materials northern Cameroon. Including the city of Maroua in the Far North Region Cameroon. The specific case of Makabaye is indeed the object of this science. This work can serve as a guide, and why not valuable source of information useful to a deeper understanding of the chemical and mineralogical characteristics of Makabaye clay. Judicious use of the results of this work may also lead to the formulation of the products in terracotta, with a valuation of its clays in the cosmetics industry, real estate, pharmaceuticals, and purification of vegetable oils. To achieve our results, we basically made of chemical and mineralogical analysis in the laboratory, along with a team of sworn laboratory for major tests we have done. In particular, it is the XRD X-ray analysis for the determination of mineral elements, and finally, the geochemical analysis by X-ray fluorescence, to better identify the specific chemical characteristics of the clay. We believe the views of the results obtained, absorbent properties of the clay materials, properties that can be put to good use in the purification of vegetable oils and waste water treatment.

“…Therefore the mentioned changes probably take place significantly within the SSL. YU et al (2004) found that between the total amount of Cu in soil and extractable amount of Cu by Mehlich-III solution the linear dependence exists. Also, these authors observed the proportion of extractable amount of Cu in comparison with the total amount of Cu in degraded soil more than 50 %.…”

The aim of the present work is to characterize the soil additive derived from sewage sludge as potentially economically acceptable material for agricultural production as well as for soil and environment protection. The soil additive consisting of sewage sludge obtained from the wastewater treatment plant Pannon-Víz Zrt. (Győr, Hungary) and agricultural byproducts represented by wastes from grain mill industry and crushed corn cobs was prepared using the low-capacity granulator equipment constructed by Energy Agency Public Nonprofit Ltd. (Hungary). The characterization of sewage sludge as primary composite and prepared soil additive includes the determination of physico-chemical parameters such as pH determined in suspension with distilled water, 0.01 mol/dm3 CaCl2 or 1 mol/dm3 KCl solutions, pHzpc predicted by potentiometric titration and ProtoFit software, water holding capacity (WHC), cationexchange capacity (CEC) and total organic carbon (TOC). The elemental analysis by X-ray fluorescence spectrometry revealed that sewage sludge as well as prepared soil additive contain significant amount of Zn and Cu as important microelements in plant nutrition. Also, it was found that prepared soil additive represents the considerable source of a significant proportion, strong bound and in this way gradually released microelements. Obtained results suggest on the application potential of prepared soil additive in agricultural production as well as in remediation and reclamation of contaminated or degraded soil.
