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 common practice of microbiological oxidation of organic pollutants in the effluents of organochemical and petroleum-based industries is not effective in mineralizing chlorinated phenols, which are persistent and toxic to organisms even at low concentrations. Effluents containing these recalcitrant organics require tertiary treatment and catalytic wet oxidation (CWO) has shown tremendous promise in this regard. The present work emphasizes on the catalytic wet oxidation of 2-chlorophenol (2-CP) with the assistance of catalysts prepared by impregnating transition metal ions [Fe(III), Co(II

In Lebanon, same type of commercial formulations of an active ingredient from different manufacturers are registered and given the same critical Good Agricultural Practice (cGAP) as the reference formulation in spite of the fact that they differ in composition of co-formulants. The international guidelines require the performance of crop field trials for, at least, those active ingredients with claimed pre-harvest interval (PHI) of less than 7 days. Four comparative dissipation studies of 3 commercial formulations of penconazole 10% EC were performed on 4 varieties of greenhouse tomatoes un

The scope of this study is investigating the tribological characteristics of prepared bio-based thread grease from renewable sources with polymerization products from jojoba oil as additives. Accordingly, the first part in this study aims to prepare three molecular weights grades from polymerization of jojoba oil using microwave technique. The physicochemical and tribological properties of obtained polymerized jojoba including jojoba oil were determined; their tribological behavior studied in term of coefficient of friction and wear scar diameter using four ball machine. The results reveale

Wastewater is of serious concern all over the world. Categorically, Municipal wastewater occupies a big percentage of total wastewater. Several methods were introduced for treatment and many methods are still in the research phase. High cost and low efficiency possess hurdles inapplicability of advanced wastewater treatment technologies in middle and lower-income countries. In this study, a low cost and efficient biofilm reactor were evaluated as an improved method to treat municipal wastewater. A lab-scale biofilm reactor was designed in which coconut shells (BRC) and gravels (BRS) were in

This study quantified the degree of heavy metal contamination and ecological risk potential from metals concentration in urban lake sediment. The analytical method involved six geochemical indices (enrichment factor (EF), geo-accumulation index (Igeo), contamination factor (CF), degree of pollution, modified degree of contamination, & pollution load index (PLI). Sediment samples were analysed using ICP-MS. The results revealed that EF and Igeo of trace elements were in the order of Pb > Cr > Cu > Mn > Ni, whereas the order of heavy metals was Na > K > Fe > AL. Na an
