The analysis of (bio)available copper in complex environmental settings, including biological test media, is a challenging task. In this study, we demonstrated the potential of a recombinant Pseudomonas fluorescens-based biosensor for bioavailability analysis of CuSO4 and CuO nanoparticles (nano-CuO) in seventeen different ecotoxicological and microbiologial test media. In parallel, free Cu in ...

Trong bài báo này, đồng (I) oxit (Cu2O) được tổng hợp thành công từ dung dịch (II) sunfat (CuSO4), glucozơ, natri hidroxit (NaOH). Dung CuSO4 tách rác thải điện tử theo phương pháp hỏa luyện kết với thủy luyện. Vật liệu này nghiên cứu bằng các thực hiện và ảnh hưởng của pH cho thấy vào gồm NaOH glucozơ có = 12 thu Cu2O cấu trúc nano. Qua việc phân tích XRD SEM vật kích thước tinh thể tính là 8,...

nano-cufe2o4 catalysts with different cu/fe molar ratios (cunfemo(n+1.5m)) were prepared by hydrothermal method. the thermal decomposition performance of cunfemo(n+1.5m) on cuso4 were determined with tg-dsc method to evaluate its catalytic activity and the roasted product was characterized by xrd. the results showed that cunfemo(n+1.5m) had superior catalytic properties and efficiency to cuso4 ...

El presente estudio de investigación demuestra que es viable la recuperación oro y zinc en minerales marmatitico con contenido oro. Se analizó mediante diseños experimentales factoriales, utilizando los reactivos: CuSO4, AR-3418 AR-1242 como variables independientes; el resto las se mantuvieron constantes.
 Como resultado obtuvo un modelo para zinc, realizando análisis del diseño factorial...

abstract an investigation was performed in a commercial orchard in shiraz to study the effect of time of application of cuso4 and streptomycin on quality and seedlessness of grapevine (vitis vinifera l. cv. ‘siyah-e-shiraz’). the experiment was conducted as completely randomized block design with 3 replications. plants were treated with 25 mgl-1 cuso4. 5h2o and 200mgl-1 streptomycin 2,4 and 6 d...

Organik bir malzeme olan odun, odun tahripçisi organizmalar tarafından bozundurulmakta ve tahrip edilebilmektedir. Bu amaçla geçmişten günümüze kadar birçok emprenye maddesi geliştirilmiş halen de geliştirilmeye devam etmektedir. çalışmada, sarıçam örnekleri %0,25, 0,5, 1, 1,5 2,5 konsantrasyon seviyesinde çinko klorür (ZnCl2), nano seryum oksit (CeO2), (ZnO) bakır II sülfat (CuSO4) ile edilere...

Copper nanoparticles (Cu-NPs) are components in numerous commercial products, but little is known about their potential hazard in the marine environments. In this study the effects of Cu-NPs and soluble Cu on juvenile Epinephelus coioides were investigated. The fish were exposed in triplicate to control, 20 or 100 µg Cu L(-1) as either copper sulphate (CuSO4) or Cu-NPs for 25 days. The growth p...

nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study  cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

Copper sulfates (CuSO4) are widely used as the primary component of fungicides in the grape industry. The agricultural-grade CuSO4 that we collected from Chinese nationwide markets were found to be contaminated by polychlorinated dibenzo-p-dioxins and dibenzofurans and high levels of polychlorinated biphenyls (Σ19PCBs: 0.32~9.51 ng/g). In the following research, we studied the impact of CuSO4 a...

Three chick experiments were conducted to investigate possible explanations for why pork liver provides no bioavailable Cu to chicks. Autoclaving, acid-hydrolysis, and protease-digestion increased (P < .01) Cu bioavailability in pork liver to 32, 46, and 63%, respectively, from virtually 0% of the Cu in unprocessed pork liver (relative to CuSO4, which was set at 100%). Addition of EDTA at 200 m...
