Adsorption is a major industrial separation technique for the purification of effluent media. It is a mass transfer operation through which a solid material can selectively remove dissolved components from an aqueous solution by attracting the dissolved solute to its surface. Therefore, it involves the...
Sodium chloride (NaCl), Calcium Chloride (CaCl2) and chloroform (A.R grade) were purchased from Finar Chemicals. Aqueous solutions of the SAILs and brines were prepared by using degassed Millipore-grade water. Three types of brine solutions were prepared for adsorption studies carried out in this...
which result in the sprawling of buildings in the outskirts. Ibadan is a major city in southwest part of Nigeria that was for a long time allowed to grow without a master plan (Areola and
6. The underlying reason regarding why we are headed toward debt problems is different from in the past. We now are dependent both on oil products and electricity, two very concentrated carriers of energy, instead of the more diffuse energy types used in the past. Our problem is that these ...
The intrusive rocks in the study area are more developed and mainly distributed in the central part of the study area. This region is influenced by the plateau temperate semi-arid climate [28], with an average annual temperature of 2 °C and the highest (12 °C) and lowest (−8 °C...
Based on the energy dissipation theory, the damage variable model was further established, the damage variable can reasonably describe the damage evolution of crack granite under dynamic-static loading. Keywords: SHPB tests; double-flaw rocks; dynamic and static combination; fractured rock; energy ...
The rainfall distribution is not uniform, and the majority of the rain occurs during the monsoon period, which lasts from mid-July–September, with some occasional rainfall in winter. The aquifer of the study area is unconfined, having a bottom of igneous and metamorphic rocks of a Precambrian...
Bands of the Wayanad group are found in the northern part of the district, while the rocks of south and southeast are formed by the charnockite group [15]. The northcentral part is composed of a peninsular gneissic complex and the southcentral part is of the migmatite complex. Figure 1. ...
The Silurian is mainly distributed in the central and southeastern regions of the study area and is dominated by neritic clastic rocks and carbonate facies. The control area of this system is large and prone to geological disasters. The Sinian system is mainly distributed in the central and ...
was observed at depths D3 and D4, indicating that diuron tends to leach more in the commercial formulation, especially when applied as binary and ternary mixtures. From depth D5 to D7, diuron was no longer detected, whether applied in isolation or as mixtures, for both types of ...
