“…Moreover, the range of analysis, so the lowest and the highest determinable concentrations of abovementioned individuals (2 µg/dm 3 of clotrimazole to 2270 µg/dm 3 of telmisartan) can be considered as satisfactorily wide [34]. The same analytical technique was used for the analysis of 30 psychoactive pharmaceuticals, illegal drugs and their metabolites 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA), methylenedioxyethylamphetamine (MDEA), N -methyl-1,3-benzodioxolylbutanamine (MBDB), cotinine, methamphetamine, amphetamine, 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH), cocaine, benzoylecgonine, cathinone, codeine, risperidone, oxycodone, 6-acetylmorphine, lysergic acid diethylamide (LSD), 2-oxy-3-hydroxy-LSD (OH-LSD), ketamine, norketamine, mephedrone, methylphenidate, tramadol, midazolam, venlafaxine, oxazepam, citalopram, buprenorphine, norbuprenorphine, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP, methadone) in hospital effluents and wastewater after treatment [37]. Many other authors have reported the use of the mentioned SPE LC–MS/MS [38, 39] and that is why the technique may be considered as one of the most suitable for sewage sludge analysis.…”

This article presents the most popular methods of sewage sludge management and analytical techniques which could be a powerful tool in designing new sewage sludge management methods. Chemical analysis is also described as a vital point at the subsequent stages of technological processes control and sewage sludge quality assessment. It is also an instrument essential to maintaining control of processed sewage sludge introduced to the environment as ready-to-use materials. The sludge management method is conditioned by the compliance with legal acts concerning sludge management. The most important of these contain information regarding allowable concentrations of pollutants which can be released into the environment, and the most important declarations concerning sewage sludge management. Various analytical techniques and preparation methods that can be used during the monitoring of the managed and processed sewage sludge are described. The most important are chromatographic techniques, methods based on inductively coupled plasma, and mass spectrometry based methods.Graphical abstract

“…The second step of the application simulated more real conditions for the addition of ferrate-zeolite tablets on wastewater that also contained fragments of SARS-CoV-2 virus. Nowadays, municipal wastewater after traditional treatment in water resource recovery facility (WWTP) includes a wide range of various hardly degradable micropollutants (Birošov a et al, 2014;Macku ľak et al, 2017Macku ľak et al, , 2019. Concentrations of these micropollutants in water are usually very low, but their presence is undesirable and endangers the environment or animal and human health.…”

Improper and insufficient treatment of infectious hospital wastewater could seriously endanger public health and the environment. Ferrate(VI), a strong oxidizing, disinfecting, and coagulating agent, has the potential as a green solution for decontamination of water and wastewater. In this paper, electrochemically prepared potassium ferrate (K2FeO4) with high purity was successfully encapsulated and applied to the water contaminated by SARS‐CoV‐2. Natural zeolite was chosen as an appropriate ecological material for ferrate encapsulation. The stability of encapsulated ferrate (in tablet form) was monitored for an extended time period (290 days) and has significantly increased in contrast with free potassium ferrate by almost 30%. Subsequently, the K2FeO4 encapsulated with zeolite in tablet form was applied to the water and municipal water samples containing the SARS‐CoV‐2 virus. The removal efficiency reached up to 98.5% and 86.7%, respectively, under natural conditions. Combination of environmentally friendly oxidizing agent and natural excellent adsorbent leads to the creation of very effective water treatment matter. These findings are essentially immediate and especially important for immediate water treatment in urgent situations such as natural disasters or military conflict.Practitioner Points Electrochemical preparation of oxidizing agent, K2FeO4, in high purity by own constructed electrolyzer. Encapsulation of ferrate(VI) to natural zeolite threefold improving the stability during 9 months. SARS‐CoV‐2 virus was successfully removed from various contaminated types of water. High degradation efficiency of virus fragments by Fe(VI) was achieved without additional water adjustment, in natural pH range.
