The polymeric Si-O-Al network gives the geopolymer ion exchange property, allowing the immobilization of heavy and radioactive metals within the material matrix. Due to the geopolymer's characteristic of immobilizing heavy metals in its matrix, this project aims to evaluate the geopolymer's ability to absorb heavy metals in contaminated water. For this, samples of porous geopolymers with magnetic charges in concentrations of 1, 2 and 3% were produced. And, subsequently, toxic metal solutions were made, such as Chromium, Cadmium and Lead at a concentration of 3ppm, then the sorption was carried out using the static method, where 0.5 g of the gepopolymer was dispersed in 25 ml of contaminated water and left stirring for 5 minutes, with the aid of a mechanical stirrer, and left to rest for 24 hours for the geopolymer to settle and the supernatant to be collected (this procedure was performed for geopolymers with and without magnetic charges). Afterwards, the treated water was analyzed by the atomic absorption technique, in order to investigate the geopolymer's sorption capacity. All tests were performed in triplicate and the mean, standard deviation and 95% confidence limit were evaluated to determine the reliability of the results.","PeriodicalId":438033,"journal":{"name":"Brazilian Journal of Experimental Design, Data Analysis and Inferential Statistics","volume":"277 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122123721","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}

In this type of laboratory, the improvement corresponds to the reduction of variability, which guarantees greater reliability of the analytical results, and one of the ways to achieve this reduction is to carry out an experiment. In this work, a practical example of a chemical industry will be presented in which the experiment allowed to quantify the contribution of the steps: (I) preparation of the samples, (II) of the different technicians and (III) the measurement itself. An experiment with random factors and a hierarchical factor (nested factor) was used and the results were analyzed using an ANOVA. From the analysis of the results, it was identified that the major contributor to the final variability was the preparation of the samples. Efforts were directed at this stage, with a review of the procedure and training of technicians, which provided a general improvement in the reliability of the analytical results. With a second similar experiment it was possible to prove the effectiveness of the improvement actions.","PeriodicalId":438033,"journal":{"name":"Brazilian Journal of Experimental Design, Data Analysis and Inferential Statistics","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121395383","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}
