Novel adsorbents for the removal of toxic cadmium ions from polluted water.

Cadmium is one of the most toxic heavy metal ions found in wastewaters and its remedial methods are globally investigated. Removal methods based on biomaterials as adsorbents are proving to be simple, effective and eco-friendly. In the present investigation, bio-adsorbents derived from plant stems (CRSP) and its active carbon (CRAC) are observed to have good adsorption for toxic cadmium ions.

Synthesis and characterization of two known and one new impurities of dolutegravir: evaluation of certain intermediates against SARS CoV-2 O-ribose methyltransferase (OMTase).

Besides its use against HIV infection the marketed anti-retroviral drug dolutegravir attracted attention as a potential agent against COVID-19 in multiple AI (artificial intelligence) based studies. Due to our interest in accessing the impurities of this drug we report the synthesis and characterization of three impurities of dolutegravir one of which is new. The synthesis of O-methyl ent-dolutegravir was accomplished in three-steps the first one involved the construction of fused 1,3-oxazinane ring.

Stem powder and its active carbon of plant for lead (II) removal: application to treat battery-based industrial effluents.

Stem powder and its active carbon plant are identified to have strong adsorptivity for lead ions. The bio-sorbents are characterized by conventional methods including XRD and FTIR analysis. These biomaterials are investigated for their maximum adsorption for lead ions by optimizing the extraction conditions.

Simultaneous removal of lead and cadmium ions from simulant and industrial waste water: using plant materials as sorbents.

The merit of this investigation is that simple and effective bio-sorbents based on plant materials with high sorption capacities, are developed for the simultaneous removal of the toxic Pb and Cd at neutral or nearly neutral pHs. These sorbents are successful in water remediation of Pb and Cd ions from real effluents from industries. These findings have great significance as the identified bio-sorbents are simple, effective and renewable in extracting highly toxic lead and cadmium ions from the effluents from industries or polluted water.

High resolution and high throughput analytical methods for d-tagatose and process related impurities using capillary electrophoresis.

d-tagatose is a low calorie multifunctional rare ketohexose sugar with sweetness similar to that of sucrose and it has high potential benefits for food and pharmaceutical industries. It is found in traces in some fruits as a natural component. In view of its high demand as a substitute for sugar, mass production of d-tagatose through enzymatic conversion of Lactose to d-tagatose is adopted.

Synthesis of nanoZrO via simple new green routes and its effective application as adsorbent in phosphate remediation of water with or without immobilization in Al-alginate beads.

Nano particles of ZrO of average size 10.91 nm are successfully synthesized via green routes from a solvent blend of water and ethylene glycol (4:1 v/v). Bio-extract of seeds of Sapindus plant is employed as stabilizing and/or capping agent and homogeneous method of precipitation is adopted to generate the precipitating agent.

Sequential synergetic sorption analysis of Gracilaria Rhodophyta biochar toward aluminum and fluoride: A statistical optimization approach.

The present work proposes the synthesis of robust biochar from Gracilaria Rhodophyta red weeds for sequential removal of Al(III) and fluoride from wastewater. The sorption experiments have been modeled by preliminary optimization of operational parameters using 2 factorial statistical modeling. The model has estimated an optimum sequential synergetic removal of 44.

Preparation, characterization and feasibility analysis of methyl ester of Sesbania seeds oil (MESSO) as alternate liquid dielectrics in distribution transformers.

The methyl ester of Sesbania seed oil (MESSO) was prepared using the transesterification method. The conditions for obtaining the maximum yield of the ester were optimized. The yield was 93.

A sensitive and high throughput method for the analysis of d-psicose by capillary electrophoresis.

d-Psicose/allulose is a rare sugar and it has high potential benefits for pharmaceutical and food industry. The existed analytical methods have its own limitations to quantify fructose and d-psicose mixtures. Hence there is a need for the development of an effective, efficient and sensitive analytical method for quantification of d-psicose in presence of other sugars.

Enhanced removal of chromium (VI) from wastewater using active carbon derived from Lantana camara plant as adsorbent.

Activate carbon prepared from the stems of Lantana camara plant (ACSLC) is investigated as adsorbent for the removal of chromium (Cr) (VI) from polluted water using batch methods of extraction. Various extraction conditions such as pH, initial concentration of Cr (VI), sorbent dosage, temperature, equilibration time and presence of co-ions are optimized. The adsorption capacity is found to be 26.

Extraction of Phosphate from Polluted Waters Using Calcium Alginate Beads Doped with Active Carbon Derived from Plant as Adsorbent.

An adsorbent prepared by entrapping active carbon derived from the stems of plant in the calcium alginate beads (CABAA) has been investigated for its adsorption nature towards the removal of phosphate by varying various physicochemical parameters. Surface morphological studies are made using FTIR, XRD, FESEM, and EDX. The sorption mechanism is analyzed using Freundlich, Langmuir, Dubinin-Radushkevich, and Temkin adsorption isotherms.
