Application of Chemically Modified Industrial Slag to As({III}) Adsorption from Wastewater: Kinetics and Mass Transfer Analysis.

In the present study, brick kiln slag (BKS) has been utilized for low concentration As(III) adsorption in batch mode. BKS was modified with H2SO4 (SA) and NaOH (SB) for enhancing As(III) uptake capacity. Maximum adsorption capacity (13.

Recent trends in the application of modified starch in the adsorption of heavy metals from water: A review.

The presence of polyfunctional ligands on the bio-macromolecules acts as an efficient adsorbent for heavy metal ions. Starch is one of the most abundant, easily available and cheap biopolymer of plant origin. However, native starch exhibits significantly low adsorption capacity due to the absence of some essential functional groups like carboxyl, amino or ester groups and is thus modified using various reaction routes like grafting, cross-linking, esterification, oxidation and irradiation for addition of functional groups to increase its adsorption capacity.

Simultaneous oxidation and esterification of cellulose for use in treatment of water containing Cu(II) ions.

Cellulose powder was modified with Sodium Hypochlorite (NaOCl) and Octenyl Succinic Anhydride (OSA) in different proportions. The adsorbents were characterised by BET, FTIR, XRD, TGA and SEM. Intrinsic viscosity increased with degree of substitution (DS).

SYNTHESIS AND CYTOTOXIC EVALUATION OF SOME 2-{4-[(2-OXO-1,2-DIHYDRO-3H-INDOL-3-YLIDENE)METHYL] PHENOXY}-N-PHENYLACETAMIDE.

A series of 2-oxindole derivatives were synthesized and evaluated for cytotoxic activity against different human and murine cancer cell lines and cancer chemopreventive activity. Among the tested compounds VS-06, 08, 12 and 17 displayed cytotoxic activity in the range of 5.0 to 8.

SYNTHESIS OF IMIDAZO[2,1-b][1,3,4]THIADIAZOLE DERIVATIVES AS POSSIBLE BIOLOGICALLY ACTIVE AGENTS.

A series of 2-(4-methylbenzyl)-5,6-substituted-imidazo[2,1-b][1,3,4]thiadiazole derivatives were synthesized, characterized and evaluated for antiproliferative activity and cancer chemopreventive activity. Results showed that molecules with formyl and thiocyanate substiments at the 5 position exhibited an increase in activity against the full panel of 60 human tumor cell lines at a minimum of five concentrations at 10-fold dilutions. Derivative 22 displayed significant in vino anticancer activity against colon cancer (MID GI₅₀ = 0.

Synthesis, anticancer and cytostatic activity of some 6H-indolo[2,3-b]quinoxalines.

Various 6-aralkyl-9-substituted-6H-indolo[2,3-b]quinoxalines were synthesized by reaction of 1,5-disubstituted 2,3-dioxo-2,3-dihydroindole and orthophenylene diamine. Appreciable anticancer activity of compounds 5b, 5d, 5g and 5l at various cell lines among 59 human tumor cell panels was observed. All the synthesized compounds were evaluated for cytostatic activity against human Molt 4/C8 and CEM T-lymphocytes as well as for murine L1210 leukemia cells.
