Research Journal of Chemistry and Environment (ISSN:0972-0626) is a monthly peer-reviewed scopus-indexed journal from 2007 to Present. The publisher of this journal is the Journal of International Congress of Chemistry and Environment. RJCE is committed to gathering and disseminating excellent research achievements. The journal welcomes all kind of research/review/abstract papers regarding Engineering subjects including Earth and Planetary Sciences, Environmental Science, Chemical Engineering, Agricultural and Biological Sciences, Renewable Energy, Biochemistry.
The purpose of this study was to explore the impact of two different extraction times (15 min and 30 min) on the extraction yield of phytochemicals and antioxidant activity of various Benjakasorn formula mixed with Chamomile, Goji berry and Stevia. Decoction extracts were tested for TPC, TFC, DPPH radical scavenging, and FRAP antioxidant power. Performance of multi-herb preparations was prominent, the highest yield (26%), TPC (145 mg GAE/g), TFC (200 mg QE/g), and FRAP (145 mg TEAC/g) were reached at 30 min for BJKCMLBSR indicating synergistic effect. Single herbs were somewhat inconsistent in
Read MoreModification of asphalt with nanocomposite now it's considered a new approach to improvement of the asphalt characteristics, Chalcogenide d-element it will be used here as an improver to asphalt. The physical and mechanical characteristics of asphalt were examined in this paper, along with comparative rheological testing on binders and mechanical tests for unmodified and modified asphalt with nanocomposite (ZnO/PMMA). In order to increase its performance, a ZnO/PMMA nanocomposite was added to asphalt (60/70) and binders in different amounts (0.2%, 0.4%, 0.6%, 0.8%, and 1%). It was discovered t
Read MoreVarious commercial thermoplastic polymers, including styrene-butadiene rubber (SBR), polyacrylonitrile (K), polystyrene (PS), polypropylene (PP), and polychloroprene (PC), are employed to modify two types of asphalt: asphalt 60/70 Suez (L) and asphalt 80/100 Alex (H). The optimal ratio of polymer additives, introduced using a hot mixing process at temperatures between 150°C and 170°C, was determined based on the measurements of penetration, softening point, penetration temperature susceptibility (PTS), and penetration index (PI) for the cooled blended formulations. For asphalt L, the ideal p

Every resin was utilized as an additive, combined with a high-temperature hardener, to modify two types of locally available asphalt (designated M and N types) with varied constituents. The study assessed the performance of these epoxy resin-asphalt mixtures in enhancing critical properties such as penetration, softening point, penetration temperature susceptibility (PTT), and penetration index (PI). These improvements were analyzed ba
Read MoreSulfadiazine (SDZ) is a pharmaceutical pollutant frequently detected in water, posing significant health and environmental risks. To address this issue, the current research explore the use of a novel adsorbent, date seed-based activated carbon (DSAC), for the effective removal of SDZ. DSAC was optimized using response surface methodology (RSM) under preparation conditions of 2.30 minutes activation time, 490 W radiation power, and an impregnation ratio (IR) of 1.60 g/g, achieving a estimated SDZ removal of 94.30% (experimental: 90.70%; error: 3.90%) with a DSAC yield of 26.22% (experimental:
