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 current study focuses on the pollution of the Netravathi River, Gurupura River, and Baggundi Lake in the Dakshina Kannada District, which is highly polluted as a result of illegal or unauthorized discharge of domestic wastewater into these rivers. A study was carried out to assess the quality and quantity of sewage water generated in the Baikampady Industrial Area, Mangaluru, alongside an initial survey to examine the types and nature of industries operating within the area. Sewage water samples were collected from 20% of industries in each category; i.e., treated sewage and untreated sewa
Read MoreTreatment of industrial wastewaters by conventional methods requires skilled labours, external energy, high operation cost and maintenance cost, thereby creating a need for efficient eco-friendly and less expensive treatment method. The Present study focuses on treatment of industrial wastewater from paper and pulp industry, textile industry and pharmaceutical industry by using soil biotechnology. The lab scale model was set up using granular media like soil, sand and gravels. The experiments for treatability study were carried out with and without earthworms. The Eisenia fetida Earthworms wer
Read MoreThe 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

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
