Herein, we loaded cobalt-based zeolite imidazolate frameworks, ZIF-67 (Co), onto commercial filter paper to prepare catalytic (ZFP) for the in situ degradation of bisphenol A (BPA) water by activating peroxymonosulfate. The results showed that (Co) was densely and uniformly distributed on surface paper. prepared ZFP could effectively degrade BPA through a gravity-driven filtration process. Spec...

Chloride and carbonates have the potential to impact pathway, kinetics, and efficiency of oxidation reactions, both as radical scavengers and as metal complexing agents. Traditionally, it is assumed that they have an overall negative impact on the activated persulfate performance. This study investigated the influence of carbonates and chloride on the reactivity of persulfate for three differen...

Removal of natural organic matter (NOMs) from actual water is a major challenge in the context worldwide pollution resources. The removal humic acids system combining biochar adsorption and ultrasonic persulfate oxidation was studied this paper. effects addition, concentration initial pH were investigated. A high rate up to 92.5% achieved for combined biochar/ultrasonic/persulfate system, versu...

With the increasing industrial production, there was a significant number of toxic and harmful hydrogen sulfide (H2S) gas generated. Due to activities, converting H2S from waste process is environmentally attractive. This paper focuses on conversion elemental sulfur (S°) other species (i.e., sulfite ion (SO32-); sulfate (SO42-) using Fenton reagent. The effects some reaction parameters such as ...

objective(s) the aims of present study were to elucidate the effect of nahs as a h2s donor on precontracted rat trachea smooth muscle, role of epithelium and nitric oxide in this action. materials and methods tracheal rings from male adult wistar rats were isolated and mounted in an organ bath containing krebs–henseleit solution under 1.5 g resting tension and contractions were recorded isometr...

from june 1992 to march 1993, a group of patients suffering from different types of warts were treated with intralesional injections of bleomycin sulfate. this study reviews the literature concerning this modality of treatment and the pathophysiology and immunohistopathology of warts and options for treatment. in this prospective study, a combination of a i mg/ml solution of bleomycin in distil...

Oceans dominate emissions of dimethyl sulfide (DMS), the major natural sulfur source. DMS is important for the formation of non-sea salt sulfate (nss-SO42-) aerosols and secondary particulate matter over oceans and thus, significantly influence global climate. The mechanism of DMS oxidation has accordingly been investigated in several different model studies in the past. However, these studies ...

Anaerobic microorganisms play key roles in the biogeochemical cycling of methane and non-methane alkanes. To date, there appear to be at least three proposed mechanisms of anaerobic methane oxidation (AOM). The first pathway is mediated by consortia of archaeal anaerobic methane oxidizers and sulfate-reducing bacteria (SRB) via "reverse methanogenesis" and is catalyzed by a homolog of methyl-co...
