In this work, Symplocos racemosa (Lodh) biowaste (SR) was chemically fabricated to make it a sustainable material for detoxifying cationic pollutants from waste-water by green technology using methylene blue (MB) dye as a test case. Morphological changes that occurred in SR were observed by SEM, EDX, XRD, and FTIR methods. Batch adsorption experime...

The adsorption efficiency of cheap, ecofriendly, and easily available agro-waste, Trapa natans (Chestnut) and Citrullus lanatus (Watermelon) peels, has been investigated in their native forms (TNAT and CLAN) as well as citric acid impregnated forms (C-TNAT and C-CLAN), respectively, for the detoxification of toxic, deleterious, and carcinogenic Eos...

Many reports of detrimental organic dyes in industrial sewages incited the researchers to accomplish some quick, cost-effective, and precise ways for dye eradication. Continuing this research chain, the latest study aimed to exclusively eliminate methylene blue dye (MB) from industrial wastewater using black C. arietinum husk powder as a cost-effec...

Redistribution of anions and cations creates an electrical imbalance in ice grown from electrolyte solutions. Movement of acidic and basic ions in cooling solutions can permanently change the pH of frozen and unfrozen parts of the system, largely. The extent of pH change associated with freezing is determined by solute concentration and the extent...

Vegetables are generally boiled for cooking or stored in refrigerators. This results in loss of their nutritional values. Ascorbic acid is one of the important nutrients for human health. In this study, Ascorbic acid (vitamin-C) content of various vegetables of Pakistan was determined, and effect of boiling and freezing were compared with natural A...

In present study, alpha tocopherol was determined in different edible seeds and nuts of Pakistani origin by reversed phase high performance liquid chromatography employing UV/Visible detector. Alpha tocopherol is an important constituent of vitamin E. Extraction of sample oil was carried out by Soxhlet method using n-hexane as a solvent. The maximu...

Agro-waste materials have carboxylic and phenolic groups that play the main role in metal adsorption. The advantages of these materials include easy availability, low cost, and reasonable metal removal capacity. One of the materials (usually considered as waste) is pea waste (pods). Present work comprises adsorption of chromium from aqueous solutio...
