Transport mechanisms and a mathematical model for a continuous countercurrent predispersed solvent extraction (PDSE) process are proposed in this paper. Solvent extraction using polyaphrons provides enhanced mass transfer ...

A plant‐based natural surfactant with potential applications in the remediation of contaminated soils was obtained from the dry fruit pericarps of Sapindus mukorossi,. Kinetics of microbial growth in the natural surfactant ...

Currently, the mechanisms underlying the effects of nitrogen on nodulation and nitrogen fixation of leguminous plants remain uncertain. To further investigate the relationship between nitrogen with nodulation and nitrogen ...

Surfactant based soil washing and flushing is an emerging technology for Superfund site remediation in the United States. The presence of surfactants in the wastewater, however, poses challenging problems for subsequent ...

Studies are presented investigating the ability to enhance aryl nitro-reduction processes in sediments through electron donor addition. In particular, high molecular weight (starch and guar gum) and/or low aqueous solubility ...

The fate of 2,4,6-trinitrotoluene (TNT) and TNT transformation products in two aerobic enrichment cultures was investigated. Contaminant fate was assessed through analysis of TNT and its oxygen-stable aminated derivatives ...

A pilot-scale study was conducted to evaluate the use of aerobic slurry reactors to treat soils that were highly contaminated with 2,4-dinitrotoluene (2,4-DNT) and 2,6-dinitrotoluene (2,6-DNT). Contaminated soils were ...
