Silver nanodispersion stabilized by sodium alginate (Ag0-AlgNa) was chosen as an antibacterial agent. Ag-doped Zr(IV) and Al(III) oxyhydroxides adsorbents were synthesized by combination of sol-gel and reagentless plasma-chemical methods. The offered technique allows to receive the highly homogenized metal oxyhydroxides sols with Ag0 impurities, which is confirmed by the presence of a peak at 410 nm in composite sols. The absence of free Ag+-ions in sols during their aging proves full introduction of Ag0 and Ag+ additives into metal oxyhydroxides structure due to the formation of silver chloride complexes and the partial hydrolysis of Ag+ with following formation of Ag20. XRD-patterns showed that the resulting composite modified by AgO-AlgNa additive has weak crystalline phases at 38.1° and 44.30° and 32.3°, 46.3° and 57.70°, which correspond to Ag0 and Ag2O phases. Proposed method allows to obtain nanostructured adsorbents, which are characterized by high surface area from 310 to 540 m2/g and pore size >2 nm with a point of zero charge at pH=6.0÷6.8. Water treatment test of adsorbents shows their high efficiency to reduce total solids, manganese ions, colony count 22°C and Coliform bacteria in the natural underground water.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123187769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These different local areas on the cleavages show semiconductor and metallic nature. STS spectra allow us to determine the occurrence of an additional metallic component - silver, except, indium in the interlayer gap of the crystal on the local level.

Ar13impacts induced a few times higher cluster temperatures and an order of magnitude higher sputtering yields as compared to Ar1.
