1. Electrosynthesis of persulfate and hydrogen gas with boron doped diamond as the anode material
University essay from KTH/KemiteknikAbstract : The efficiency of boron-doped diamond electrodes (BDD) has been investigated by electrolysis of an aqueous solution containing sodium sulfate. A Synthesis StarterKit from Condias was used, which contained the BDD anode with an active surface area of 3.14 cm2, and electrosynthesis was performed in a batch mode reactor. READ MORE

2. Chemical degradation of PFAS using hydrogen peroxide and persulfate
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : PFAS are a group of relatively newly discovered man-made pollutants. PFAS contains a C-F bond which is one of the strongest bonds in organic chemistry. Therefore, PFAS are not easily degradable and, once release into nature, are very persistent. READ MORE

3. Method development of total oxidizable precursor assay for perfluoroalkyl acid precursors in domestic sludge
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Per- and polyfluoroalkyl substances (PFASs) are persistent organic pollutants used in industrial applications and are globally distributed in the environment. A group of PFASs that are difficult to measure with today’s method are perfluoroalkyl acid precursors (PFAA precursors) that, when degraded, serves as indirect sources of PFAAs. READ MORE

4. Removal of per- and polyfluoroalkyl substances from drinking water using ozonation
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Per- and polyfluoroalkyl substances (PFASs) are a broad group of man-made chemicals which are persistent, bioaccumulative and toxic. Due to their unique physicochemical properties PFASs are used in various industrial processes and consumer products. READ MORE

5. Carboxylated Cellulose Nanocrystals Extraction from Kraft Pulp Using Ammonium Persulfate as Low Cost Source & Sustainable Method for High Quality Flexible Packaging Bio-coating
University essay from Lunds universitet/FörpackningslogistikAbstract : One of the leading challenges presented in 21st century for packaging industry is to address the growing environmental problems related to non-renewable flexible packaging. This leads to new growing interest in bio-based materials, among them cellulose nanocrystals (CNCs), which have already shown good performance in improving anti-fog and oxygen & water vapor barrier properties when applied to flexible film.
