Abstract

Background: Normal skin flora and suboptimal skin antisepsis are the primary drivers of healthcare-associated infections (HAIs). Antimicrobial persistence of preoperative skin preparation is necessary to limit microorganisms on the skin and help minimize their entry into an incision or device-insertion site after application.Aim: To assess the antimicrobial persistence of two preoperative skin preparation solutions.Methods: A randomized, single-centre, partially blinded, clinical study was conducted in 103 healthy volunteers to evaluate the persistent antimicrobial properties of BD ChloraPrep™ (2% w/v chlorhexidine gluconate [CHG] + 70% v/v isopropyl alcohol [IPA]) and BD PurPrep™ (8.3% w/w povidone-iodine [PVPI] + 72.5% w/w IPA) skin preparations out to 7 days and 96 h, respectively, on abdomen and groin testing sites. An additional 32 healthy volunteers participated in a neutralization procedure to ensure that the study recovery solution was non-toxic to microorganisms, and a spore-recovery procedure to demonstrate that microorganisms could be successfully recovered from the PVP-I+IPA film-forming product.Findings: Both CHG+IPA and PVP-I+IPA produced a mean bacterial log10 reduction >2 and >3 on the abdomen and groin, respectively, 10 min after application. CHG+IPA maintained antimicrobial persistence out to 7 days post application, whereas PVP-I+IPA maintained antimicrobial persistence out to 96 h post application, the longest time-point selected for this product.Conclusion: CHG+IPA and PVP-I+IPA were both found to be effective, persistent antiseptic skin preparations. Overall, skin irritation was uncommon, and only one adverse event occurred following product application, which was not considered product-related but was considered procedure-related.

Abstract

Environmental context: Photocatalytic TiO2 materials are good prospects in water quality treatment due to their stable chemical properties and limited secondary pollution. TiO2 photocatalytic material prepared with biochar as a carrier can greatly improve the photocatalytic efficiency of CrVI, and the removal rate of CrVI can reach 84.4%. This study shows that biochar-supported TiO2 photocatalytic composites are feasible for the green and efficient removal of CrVI from an aqueous phase. Rationale: TiO2 has great application prospects in the treatment of chromium-containing wastewater due to its photochemical stability and low toxicity. Loading TiO2 on solid adsorption materials can improve the photocatalytic efficiency and solve the problem of difficult separation and recovery of TiO2. Methodology: In this study, biochar-supported TiO2 (BC-TiO2) and acid-washed biochar-supported TiO2 (HBC-TiO2) were prepared by a sol–gel method using biochar (BC) and acid-washed biochar (HBC) as adsorption carriers. The effects of various experimental parameters such as ultraviolet irradiation conditions, catalyst dose and pH on the removal efficiency of CrVI by BC, HBC, BC-TiO2 and HBC-TiO2 were investigated. The structure and morphology of the four materials were characterised. Results: The results indicated that under the optimal reaction conditions (pH = 6, dosage of biochar materials/photocatalytic composites = 5 g/6 g), the removal percentage of CrVI changed as BC-TiO2 (Light) (84.43%) > HBC-TiO2 (Light) (80.19%) > BC-TiO2 (Dark) (57.9%) > HBC-TiO2 (Dark) (52.94%) > HBC (30.06%) > BC (14.66%). Loading TiO2 on biochar materials improved the specific surface area and increased the reaction sites when compared with BC and HBC. Discussion: This study shows that BC-TiO2 is more suitable to remove CrVI from an aqueous system because of its high removal efficiency. The enrichment of CrVI on the biochars and the close contact between the biochar and TiO2 through the Ti–O–C dense heterojunction promote the interfacial transfer of CrVI, which is the key to the removal of CrVI. This study has great significance for the treatment of chromium-containing wastewater by photocatalytic composites. Environmental context.

Abstract

Environmental context Photocatalytic TiO2 materials are good prospects in water quality treatment due to their stable chemical properties and limited secondary pollution. TiO2 photocatalytic material prepared with biochar as a carrier can greatly improve the photocatalytic efficiency of CrVI , and the removal rate of CrVI can reach 84.4%. This study shows that biochar-supported TiO2 photocatalytic composites are feasible for the green and efficient removal of CrVI from an aqueous phase. Rationale TiO2 has great application prospects in the treatment of chromium-containing wastewater due to its photochemical stability and low toxicity. Loading TiO2 on solid adsorption materials can improve the photocatalytic efficiency and solve the problem of difficult separation and recovery of TiO2 . Methodology In this study, biochar-supported TiO2 (BC-TiO2 ) and acid-washed biochar-supported TiO2 (HBC-TiO2 ) were prepared by a sol–gel method using biochar (BC) and acid-washed biochar (HBC) as adsorption carriers. The effects of various experimental parameters such as ultraviolet irradiation conditions, catalyst dose and pH on the removal efficiency of CrVI by BC, HBC, BC-TiO2 and HBC-TiO2 were investigated. The structure and morphology of the four materials were characterised.
