Heavy metals' recalcitrance in wastewater has been shown to be a difficult issue. Further, drinking water quality must be at its highest for human health to be at its best; nevertheless, a number of human activities are continuously degrading it, which has an effect on human health either directly or indirectly. Because heavy metals are the primary causes of many chronic illnesses and have a tendency to bio accumulate, they are giving rise to a lot of worries. Technologies from all over the world are being developed to address the demand for clean drinking water. The objective of the current study is to raise awareness of the need to remove dangerous dense metals from various types of wastewater and the application of modified graphene nanocomposite for their adsorption-based removal. Graphene-based nanocomposite materials have been picked for this application due to their large surface area, superior mechanical strength, and reactivity towards polar and nonpolar contaminants for the electrostatic emission of the heavy metal ions arsenic (As)","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70702015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this piece of work, series of podands are used with triethylene and tetraethylene glycol chains having benzonitrile (PBT3, PBT4), anthraquinone (PAT3, PAT4) and naphthyl (PNT3,PNT4) end groups. Extraction and transport studies performed with amino acids: glycine, valine and threonine using these receptors. From the results, it is observed that the extraction efficiency of PBT3 and PBT4 is double than PNT3 and PNT4 podands, and also transport ability is double in PAT3, and PAT4. Thus we conclude that the nitrile group-containing podands (PBT3 and PBT4) are better extractants as well as a carrier than PAT3, PAT4, PNT3, PNT4, in which nitrile groups is a key component for molecular recognition of glycine, valine, and threonine, which are further used in the separation of amino acids.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70702363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chemical (weight loss) and electrochemical investigations were carried out to assess the corrosion rate and percentage inhibition efficiency of the extract. The electrochemical polarization results have demonstrated that plant leaves extract functions as a mixed type inhibitor. The stability of the inhibitor is tested at elevated temperatures by weight loss method. The corrosion inhibition mechanism is interpreted through adsorption mechanism, and the LTLE components has obeyed the Langmuir adsorption isotherm for soft steel. The interaction of the components of the extract is assessed through FT-IR technique. The surface morphology, roughness and hydrophobicity in presence and absence of the extract have been characterized through SEM, AFM and water contact angle techniques respectively. The highest inhibitory efficiency is 96.21% for 24 h as recorded by weight loss method. Additionally, the DFT computations has revealed the inhibitor’s adsorption through electron donor-acceptor interactions.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"12 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70702407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current work aims to synthesize lignosulfonate grafted sodium acrylate hydrogel (LS-g-SAH) and investigate its application in urea release behaviour. The hydrogel has been characterized by different techniques. The release kinetics has been analyzed by using a UV-visible spectrophotometer. The optimized composition of lignosulfonate, KPS, and N,N’-MBA has shown the highest water absorbency of 560 g g-1 in distilled water. The equilibrium swollen LS-g-SAH 12 hydrogel has slowly released 60% of loaded urea in 24 h and followed first-order release kinetics. Soil treatment with hydrogel has shown a significant effect in reducing the water evaporation rate. It also improved the seed germination and average height of wheatgrass. The synthesized LS-g-SAH is, thus, expected to have potential application in modern sustainable agriculture.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135659490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influences of various experimental factors such as contact time, adsorbent dosage, pH of solution, initial dye concentration and temperature have been investigated. Batch adsorption studies has manifested that the maximum adsorption capacity of MB is around 99.9 mg/g in 10 min with 25 mg adsorbent mass at an initial concentration of 100 mg/L at ambient temperature of 25°C and natural pH of solution (pH = 5.8 for NiO-Mt and pH = 6.3 for commercial bentonite). The adsorption kinetics and isotherms are well fitted by pseudo-second order and Langmuir models, respectively. The thermodynamic parameters such as the changes in Gibbs free energy, enthalpy, and entropy are determined.

With consideration of the appropriate similarity framework, the fundamental governing flow equations are converted into a system of non-dimensional equations. The bvp4c, a built-in solver of MATLAB software, is utilized to compute the numerical results of the flow problem. The present model is validated with previously published literature. The impacts of several related flow parameters on velocity, temperature, and concentration profiles have been displayed graphically. Also, the mass and heat transfer rates along with the coefficients of skin friction are calculated and discussed numerically. It is found that an increment in the thermal radiation parameter increases the fluid temperature, and the concentration gradient boosts up for the enhancement of the Soret number.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135660828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
