To understand the interactions of microwaves with dielectric materials and their conversion to thermal energy in aqueous systems, effect ionic concentration has been studied. Aqueous solutions inorganic ions were exposed (2.45 GHz) a modified oven under identical conditions. Difference solution temperatures reference pure (deionized) water was monitored each case. A significant decrease temperature observed an increase quantity ions. Experiments repeated several varying size charge. The...
Deep eutectic solvents (DES), which have low toxicity and are cost, biodegradable, easily synthesized, were used for the extraction of neutral red (NR) dye before its spectrophotometric analysis. DES, containing choline chloride as a hydrogen bond acceptor phenol donor with molar ratio 1:2, was NR from aqueous media. The possible interaction different DESs studied using density functional theory (DFT) calculations. Experimentally, UV-visible spectrophotometer quantitative most important...
Redistribution of anions and cations creates an electrical imbalance in ice grown from electrolyte solutions. Movement acidic basic ions cooling solutions can permanently change the pH frozen unfrozen parts system, largely. The extent associated with freezing is determined by solute concentration cooling. In present work, redistribution hydrogen, hydroxyl, carbonate, bicarbonate was studied during directional batch aqueous systems. Controlled employed vertically as well radially each case,...
The presence of heavy metals in industrial effluents as a single component is generally very rare. present study provides information about adsorption behaviour lead, cadmium and copper multi-component system using triticum aestivum (wheat straw) adsorbent. It has been shown that certain metal ion greatly affected by the other ions. Effects process parameters (adsorbent dose, contact time, pH, agitation speed etc.) have studied. pH 4-6 found suitable for removal. Adsorption mechanism...
Batch scale studies for the adsorption potential of novel biosorbent Phragmites karka (Trin), in its natural and treated forms, were performed removal mercury ions from aqueous solution. The study was carried out at different parameters to obtain optimum conditions pH, dose, agitation speed, time contact, temperature, initial metal ion concentration. To analyze suitability process maximum amount uptake, Dubinin-Radushkevich (D-R) model, Freundlich isotherm, Langmuir isotherm applied. values...
The objective of this study was to assess the occupational exposure mercury in dentistry and associated environmental emission wastewater Lahore, Pakistan. A total ninety-eight blood samples were collected comprising 37 dentists, 31 dental assistants, 30 controls. Results demonstrate that personnel contained significantly higher mean concentration their (dentists: 29.835 µg/L assistants: 22.798 µg/L) compared controls (3.2769 µg/L). found maximum older age group (62.8 dentists (44.3...
Novel nonlinear optical (NLO) molecules are designed in order to meet their tremendous demand the field of optics and electronics. The first attempt structural tailoring disperse orange 3 (DO3)-an azodye is made develop nineteen derivative (D1–D19). Two approaches were opted for preparing 4 groups molecules. one was extension [Formula: see text]-conjugated system second strategy use diverse electron donor acceptor unique donor-[Formula: text]-acceptor systems. Density functional theory (DFT)...
Halogenated nonfused rings containing molecular acceptors are considered widely owing to their potential be lightweight, and flexible, improve the electron mobility overall charge transfer process in organic solar cells (OSCs). Herein, we designed a new series of ring ATH1-ATH11 by modulating synthetic reference molecule ATH-R. Incorporating CN, [Formula: see text], F Cl atoms greatly impacts structures electronic properties, which could potentially enhance text]-[Formula: text] stacking,...
Complexes of enaminones; 4-N,N-diethylamine-pent-3-ene-2-one [HL1], 4-N,N-di n-propylamine-pent-3-ene-2-one [HL2] and 4-N,N-dicyclohexylamine-pent-3-ene-2-one [HL3] with Fe(II) Zn(II) ions were prepared by reacting the equimolar ethanolic solutions ligands (HL1, HL2 HL3) metal solutions. The complexes formed, characterized infrared, ultraviolet atomic absorption spectroscopy. Ligands their tested against Escherichia coli Staphylococcus aureus bacteria to assess antibacterial action using...
The present study provides information about the binding of Pb(II) ions on an eco-friendly and easily available biodegradable biomass Trifolium resupinatum. powdered was characterized by FTIR, potentiometric titration surface area analyses. FTIR spectrum showed presence hydroxyl, carbonyl amino functional groups bound with oxygen- nitrogen-containing sites (hydroxyl groups). acidic were also confirmed titrations. Effects various environmental parameters (time, pH concentration) have been...
The present study proposed the adsorption characteristics of Pb(II), Cd(II), and Cu(II) on to Sorghum bicolor L. (commonly, Charee in Pakistan) biomass from aqueous solutions. influence different process parameters, such as adsorbent dose, solution pH, contact time, agitation speed, initial metal ion concentration, were studied thoroughly evaluate optimum conditions for adsorption. Maximum all ions has taken place at pH 5.0–6.0. Langmuir, Freundlich, Temkin, Dubinin–Radushkevich isotherm...
Among a variety of microbial materials employed for biosorption, algae have added advantages non-toxic and autotrophic nature. In this study, biosorption Hg(II) was studied with red algal biomass Porphyridium cruentum. The parameters affecting such as dosage biosorbent, pH, contact time, initial metal concentration, temperature effect foreign cations in binary system were evaluated. Kinetic data described the help pseudo-first-order pseudo-second-order kinetic models. Langmuir, Freundlich,...
Abstract Agro-waste materials have carboxylic and phenolic groups that play the main role in metal adsorption. The advantages of these include easy availability, low cost, reasonable removal capacity. One (usually considered as waste) is pea waste (pods). Present work comprises adsorption chromium from aqueous solution using powder pods garden peas (Pisum sativum) batch. Important parameters like adsorbent dose, pH, contact time, agitation speed were studied. Adsorption equilibrium was...
