In the laboratory, chlorine may be prepared by oxidation of HCl with manganese dioxide: 4HCl + MnO2 → MnCl2 + Cl2 + 2H2O Hazard Chlorine is a pungent suffocating gas, exposure to which can cause irritation of the eyes, nose and throat; burning of mouth; coughing; choking; nausea, vomit...
Preparation of Chlorine: this chemical can be prepared by the electrolysis of sodium chloride dissolved in water in industry. 2 NaCl + 2 H2O → Cl2+ H2+ 2 NaOH Uses of Chlorine: this chemical is used in making plastics, solvents for dry cleaning and metal degreasing, textiles, agrochemicals...
The different detection methods cause the disagreement of water quality evaluation. This paper describes the influence of chlorine level on the COD standard solution prepared by laboratory and river freshwater sample from Qiantang River upstream in detail, and analyses the difference between the acid ...
Chlorinated compounds are ubiquitous. However, accumulation of chlorine-containing waste has a negative impact on human health and the environment due to the inapplicability of common disposal methods, such as landfill and incineration. Here we report a sustainable approach to valorize chlorine-containing...
can be used to prepare ClO2. This oxide reacts in basic solutions to produce a mixture of ClO2− and ClO3−. (17.76)2ClO2+2OH−→ClO2−+ClO3−+H2O Industrially, ClO2 is prepared by several methods, most of which involve reduction of NaClO3. For example, the reaction with HCl ...
Their presence in DW distribution systems (DWDS) can alter bacterial behaviour, characteristics, and structure, which may compromise DW disinfection. This work provides insights into the impact of methylparaben (MP) on the tolerance to chlorine disinfection and antibiotics from dual-species biofilms ...
Except the parameters have been revealed before, here we'd like to show that controllable preparation of active nano-gold catalyst can be achieved using chlorine as an indicator. By tracing the chlorine concentration in the washing step, a series of Au/Fe2O3 catalysts were prepared with co-...
Retention of sulfur, phosphorus, chlorine, and fluorine in Hanford Phase II vendor LLW glasses Twelve Hanford Site underground storage tank low-level waste (LLW) glasses with significant different compositions were prepared in laboratory crucibles at temperatures of 1140 to 1440 degrees C. The batch ...
Pulps from non-wood plants were prepared separately at the laboratory by soda-anthraquinone (AQ) process. These 19 non-wood plants had a lot of variation in chemical, anatomical and morphological properties (Ferdous et al. 2020). The chemical characteristics of some of these non-woods were ...
Herein, we modify the band gap and improve the optical properties of TiO2 via co-doping with hydrogen and halogen. The present density functional theory (DFT) calculations indicate that hydrogen is incorporated in interstitial sites while fluorine and chlorine can be inserted both as interstitial...
