The limitations of most of these treatment methods are their high operational and maintenance costs cannot effectively be used to treat wide range of such wastewater. This work describes the use of kaolinite clay as an efficient adsorbent material for anionic azo dye methyl orange removal from synthesized wastewater. Batch adsorption experiment of 200 mgL -1 azo dye methyl orange contaminant removal using kaolinite clay at different stirring speed: 100, 200, 300, 400 and 500 rpm at constant pH4 and contact time of (0 ‒ 180) minutes were investigated, thus, adsorption increases with increase in stirring speed with maximum removal of 69.90% and maximum adsorptive capacity of 3.476 mg/g at 500 rpm. The adsorption equilibrium data were well described by Langmuir>Freundlich>Koble-Corrigan whilst adsorption kinetic data by pseudo second-order>pseudo first-order>intraparticle diffusion>Reichenberg equation in the stated order based on high correlation coefficients and relatively small values of error function analyses (χ 2 , RMSE, NSD and ARE). The adsorption processes were controlled by chemisorption. The potential applicability of Alkaleri kaolinite clay from Northeast-Nigeria could be employed as a low-cost adsorbent alternative to commercial/activated carbon in the removal of azo dye methyl orange from wastewater.","PeriodicalId":15735,"journal":{"name":"Journal of Engineering and Technology","volume":"66 1","pages":"422-433"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81454251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We acquired support from the Scopus-Elsevier information base and its listed journals to download the information for this examination. The data covers 48 years of exploration. This examination is separated into five spells to analyze; year-wise, sort of reports, an arrangement of subjects, creators design transport, an association of the primary creator with the nation, and dialects of a composition, distributed from 2019 – 1972. Results: One hundred forty-six different types of documents were written by 395; 2.7% authors in eleven languages and categories in eleven subject areas published in the Scopus-Elsevier database from 20191972. Majority of 81; 55% documents scripted as articles, followed by conference papers. The first spell published 84; 57%, remaining 62; 42.4% documents published in four spells. With 47 documents, Industrial Engineering got maximum attention, Road, and Traffic with 46 documents, and Agricultural and Biological Sciences with 17documents and stand on second and third.

Usually, the aforementioned properties of a particular casting differ due to variation in composition of the moulding sand mixtures, sand grain shape and size, bonding capacity of the binder, type and quantity of additives used, etc. The present work focuses on the effect of various additives namely, marula shell powder (MSP), silica flour (SF), corn flour (CF) and shea butter (Vitellaria paradoxa) shell powder (SBSP) at different proportions. The quantity of the aforementioned additives for experimentation was varied from 1.0 to 6.0 wt.%. The specimens were tested for moisture contents, green compressive strength, permeability number, shatter index, green shear strength and compatibility. From the obtained test results, all the experimental additives were found to improve the selected moulding properties of the Dukku silica sand. However, moulding sand sample with shea butter shell power 6.0 wt.% (SBSP) and silica flour 3.0 wt.% revealed a better compaction as compared to corn flour and MSP. The presence of silica flour and SBSP in the moulding sand was found to improve sand strength and permeability. Green compression strength, shatter index, and shear strength were found to be highest for the SBSP and SF. \u0000 \u0000 Key words: Moulding sand properties, additives, silica flour, corn flour, marula shell powder, shea butter shell powder.","PeriodicalId":15735,"journal":{"name":"Journal of Engineering and Technology","volume":"16 1","pages":"24-36"},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86048986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
