Abstract
O‘zbekistonda keng tarqalgan mahalliy xomashyolar — bentonit gil, diatomit, o‘rik doni po‘stlog‘i, pomidor po‘choqi va qovoq poyasi — asosida tayyorlangan adsorbent materiallarning suvdagi og‘ir metall ionlari (Pb²⁺, Cu²⁺, Cr⁶⁺) va organik ifloslantiruvchilarni (metilenli ko‘k, fenol) ushlab qolish samaradorligi keltirildi. Turli usullari — tabiiy holat, kislotali ishlov (HCl), ishqoriy ishlov (NaOH) va termik aktivatsiya — tahlil qilindi. BET yuzasi, Langmuir–Freundlich izoterm parametrlari va qayta tiklanish ko‘rsatkichlari baholandi. Kimyoviy modifikatsiyalangan bentonit va diatomit tijorat aktiv ko‘miriga raqobatlasha oladigan tozalash samaradorligini namoyon etdi va sanoat miqyosida qo‘llash uchun istiqbolli ekanligi aniqlandi.References
