Biomass carbon derived from Tecoma capensis (TCL) was processed using pyrolysis at a controlled temperature in an eco-friendly, innovative and sustainable way to develop biomass-derived carbon material. The aim of this study is to demonstrate the facile synthesis of porous carbon compounds from biowaste and evaluate their use in supercapacitors. Various analytical methods, such as structural analysis, morphological studies and electrochemical studies, have been employed to characterize the carbon material generated from biomass. Electrochemical performance evaluation was conducted through cyclic voltammetry and galvanostatic charge-discharge studies utilizing 1 M H2SO4 and 1 M KOH aqueous electrolyte, which exhibited a specific capacitance of 238 F g-1. The outcomes of the studies suggested that the eco-friendly, straightforward process can be utilized to prepare biomass carbon for the electrochemical energy storage applications in an efficient and sustainable manner.","PeriodicalId":8494,"journal":{"name":"Asian Journal of Chemistry","volume":"12 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140423205","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}

The characteristics of the obtained activated carbon were assessed by performing energy dispersive X-ray (EDX), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopic (FTIR) techniques. The best optimum conditions for removing dye pollutants from wastewater were obtained at 30 mg/L methylene blue dye, 0.02 g of adsorbent and a contact time of 90 min. The maximum adsorption capacity of the activated carbon was 69.44 mg/g and the percentage removal achieved was more than 90%. The methylene blue dye adsorption data of the adsorbent were fitted to the Langmuir isotherm model. The prepared adsorbent was also applied for the removal of different colour dyes from real wastewater samples and found that the percentage removal was 71.3%, 62.7%, 66.3%, 68.4% and 72.0% for dark blue dye, red dye, pink dye, sky blue dye and yellow dye, respectively. These results indicated that the obtained activated carbon is highly effective and suitable adsorbent for removing different types of colour dyes and toxic organic substances from the wastewater.

These chemicals comprise 80% of the worldwide market and come in forms such as carbonate, lithium hydroxide and mineral concentrates. The use of lithium is predicted to surge by 60% in the coming years due to the proliferation of electric vehicles. This demands efficient and rapid deposit detection methods as well as economical and high-resolution exploration equipment. The quantity and geographical distribution of fossil and ore mineral deposits can be easily mapped using hyperspectral photography. Since salt lakes, oceans, and geothermal water hold the majority of the world’s lithium reserves ranging from 70% to 80%, these areas are ideal for the lithium extraction process. In this regard, there is an increase in research targeted at industrial lithium production from water resources. Recycling lithium-ion batteries is an alternative method that can be utilized to increase the production of lithium. Geothermal waters have lower lithium contents than brines and some of the processes are not suitable. Evaporation methods, solvent extraction, membrane technology, nanofiltration and adsorption can all be used to extract lithium from liquid media. Thus, lithium extraction from aqueous solutions was the focus of this review article, which aimed to provide straightforward technical solutions, low costs, decreased environmental impact and excellent selectivity for the lithium industry.","PeriodicalId":8494,"journal":{"name":"Asian Journal of Chemistry","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140478146","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}
