Removal of boron from aqueous environments (soil and water) is difficult, because it is present as B(OH)3 and B(OH)4- species. This research was done to study the sorption of boron by HDTMA-modified zeolite. The sorption of B on modified zeolite was studied as a function of pH (B concentration: 1 and 10 mg L-1) in the range of 6-9.5, and as a function of ionic strength (0.03 and 0.06 M Ca(NO3)2...
چکیده زمینه وهدف: در این مطالعه توانایی زئولیت طبیعی کلینوپتیلولیت به صورت اصلاح شده با سورفکتانت، جهت حذف MTBE از محلولهای آبی در سیستم ناپیوسته مورد ارزیابی قرار گرفت. همچنین مقایسه‌ای نیز بین زئولیت اصلاح نشده (NMZ) و زئولیت اصلاح شده با سورفکتانت(SMZ) جهت حذف MTBE از محلولهای آبی صورت گرفت. مواد و روش کار: در این تحقیق دو گروه زئولیت کلینوپتیلولیت طبیعی میانه و سمنان جهت انجام آزمایشات جذب ...
We investigated the sorption of pentachlorophenol (PCP) to a surfactant-modified clay and the solubility of PCP as a function of pH and ionic strength. Pentachlorophenol is a hydrophobic ionizable organic compound; therefore, it can exist as either a protonated or adeprotonated species. The objectives of this study were to determine differences in the sorption and solubility of the two species ...
Tetrasiklin ve diklofenakın iki farklı tarım toprağına (S1 S2) adsorpsiyon-desorpsiyon özellikleri kesikli denge yöntemi kullanılarak araştırılmıştır. Adsorpsiyon deneyleri, tetrasiklin diklofenak adsorpsiyonunda değişken parametreyi (temas süresi (5-120 dakika), başlangıç kirletici konsantrasyonu (5-300 mg/L)) optimize etmek için kullanılmıştır. toprak adsorpsiyon kinetiği, hızlı yavaş oranlar...
