Abstract
Izgudrojums attiecas uz sorbentiem, kas izmantojami dzeramā ūdens attīrīšanai, īpaši tā attīrīšanai no arsēna savienojumiem. Piedāvātais sorbents dzeramā ūdens attīrīšanai no arsēna savienojumiem satur dzelzs humīnskābju sāļus (dzelzs humātus), kas iegūti no kūdras un kuru sastāvā ietilpst dzelzs ne mazāk kā 5 % , bet oglekļa saturs ir no 20 % līdz 50 %.Paņēmiens minētā sorbenta iegūšanai satur sekojošas stadijas: (i) kūdras humīnskābes izšķīdināšana sārmu metālu hidroksīda šķīdumā, (ii) FeCl3 šķīduma pievienošana kūdras humīnskābes šķīdumam līdz vairs neveidojas nogulsnes, (iii) reakcijas maisījuma izturēšana, vēlams diennakti, (iv) filtrēšana, (v) uz filtra radušos nogulšņu mazgāšana (vēlams ar destilētu vai dejonizētu ūdeni), (vi) žāvēšana.Piedāvātais sorbents ļauj paaugstināt arsēna savienojumu sorbcijas kapacitāti un nodrošina visu ūdenī atrodamo arsēna oksidācijas pakāpju As(-3), As(3), As(5) savienojumu sorbciju.
