conclusions the findings of this study showed that the modification of natural zeolites can achieve higher adsorption capacity for organics. in addition, based on the results, natural zeolite being modified with sds as a cationic surfactant had good efficiency for the adsorption of nom. results the results indicated that sds-modified zeolite showed greatly enhanced adsorption capacity. findings...

A liquid chromatographic (LC) method for determining 14 sulfonamide (SA) (sulfanilamide, sulfadiazine (SDZ), sulfathiazole, sulfapyridine, sulfamerazine (SMR), sulfamethazine (SMZ), sulfamethizole, sulfamethoxypyridazine, sulfachloropyridazine (SCP), sulfamonomethoxine, sulfadoxine, sulfamethoxazole, sulfadimethoxine (SDM), and sulfaquinoxaline (SQX)) residues in edible catfish, shrimp and salm...

The theme of this article is to establish a basis for a physical model of optimization the kinetics of the process caustification (firing). In developing the mathematical model were used available data on the subject. The experimental part was carried out in order to find the optimal state of firing caustic magnesite at a given temperature and its reactivity to fast speed rotary kiln (FSRK) and...

We have investigated the sorption potential of three sulfonamides (SAs) in six New Zealand dairy farming soils using a modified batch equilibrium method employing 0.005 M CaCl2 as background solution. Both liquid and solid phases were extracted to analyse for the antibiotic concentrations in order to avoid underestimation that may arise a result of photolysis or biotic degradation. The experime...

BACKGROUND AND AIMS The three direct-acting antiviral regimen of ombitasvir/paritaprevir/ritonavir and dasabuvir (3D regimen) is approved for treatment of hepatitis C virus (HCV) genotype 1 infection. Drug-drug interaction (DDI) studies of the 3D regimen and commonly used medications were conducted in healthy volunteers to provide information on coadministering these medications with or without...

Gallic acid (GA) and its derivatives are anti-inflammatory agents reported to have an effect on osteoarthritis (OA). However, GA has much weaker anti-oxidant effects and inferior bioactivity compared with its derivatives. We modified GA with the introduction of sulfonamide to synthesize a novel compound named JEZ-C and analyzed its anti-arthritis and chondro-protective effects. Comparison of JE...
