A dynamic two-step anoxic/oxic process using sulfidated nanoscale zerovalent iron (S-nZVI) was employed to degrade tetrabromobisphenol (TBBPA). In the anoxic stage, TBBPA followed a four-step sequential debromination pathway and completely transformed bisphenol (BPA) with optimal S/Fe molar ratio of 0.3. S-nZVI inhibited H2 evolution preserved reducing capacity Fe(0). Fe(0), rather than formed FeS in S-nZVI, responsible for debromination. oxic product BPA attacked by •OH, dihydroxybenzenes...
As an artificial type of microbial carrier, plastic debris has been widely detected in freshwater habitats, and the potential impacts plastisphere (biofilms colonized on plastics) aquatic ecosystems have drawn increasing attention. Distinct community compositions structures biofilms natural substrates recorded environments. However, metabolic functioning was underestimated, especially In this study, effects substrate types carbon functions were studied by situ cultivation plastics (polyvinyl...
Chemical sulfidation has been considered as an effective strategy to improve the reactivity of zero-valent iron (S-ZVI). However, is a widespread biogeochemical process in nature, which inspired us explore biogenetic ZVI (BS-ZVI) with sulfate-reducing bacteria (SRB). BS-ZVI could degrade 96.3% trichloroethylene (TCE) acetylene, ethene, ethane, and dichloroethene, comparable S-ZVI (97.0%) same S/Fe ratio (i.e., 0.1). (0.21 d–1) exhibited faster degradation rate than (0.17 based on...
Iron sulfide (FeS) nanoparticles have been applied for selenite (Se(IV)) remediation in recent decades. However, the easy aggregation and oxidization of FeS hamper their reactivity. In this study, situ immobilization technology was to prepare nanoparticle-impregnated alginate composite (FeS-SA) Se(IV) remediation. FeS-SA removed 100% (0.13 mM), whereas pure nonstabilized sodium (SA) beads eliminated only 27 20% Se(IV), respectively. The removal efficiency increased 73% when stabilized used....
This study investigated the adsorption characterizations and mechanisms of lead (Pb) on biochar-derived microalgae residue (MB) produced at different pyrolytic temperatures. Six MB samples were prepared from Chlorella sp. (CB) Spirulina (SB) in temperature range 200–600 ℃, power (MP) was used as a control. The effect pH, kinetics isotherms studied for MBs, chemical analysis Pb2+-loaded MP performed by SEM-EDS, XRD, XPS, FTIR, Boehm titration. results showed that Pb2+ monolayer process....
Global climate changes have increased the duration and frequency of river flow interruption, affecting physical community structure benthic biofilms. However, dynamic responses biofilm metabolism during dry-wet transition remain poorly understood. Herein, in metabolic activities were investigated through mesocosm experiments under short-term (25 day) long-term drought (90 day), followed by a 20 day rewetting. The ecosystem metabolism, as measured gross primary production respiration, was...
Many researchers in the past decade have explored controlled synthesis of calcium carbonate with specific size, morphology, and polymorphism. This study biomimetic regulation microbially induced precipitation (MICP) via employing immobilization technology. Calcium alginate gel was used to immobilize Sporosarcina pasteurii, a urea-positive microorganism. CO32– generated driven by ureolysis reacted directly Ca2+ that cross-linked sodium produce CaCO3 precipitation. Based on SEM, TEM, XRD,...
