Thymine Adsorption onto Cation Exchanged Montmorillonite Clay: Role of Biogenic Divalent Metal Cations in Prebiotic Processes of Chemical Evolution
{{output}}
The adsorption of thymine, a key pyrimidine base of deoxyribonucleic acid (DNA) on montmorillonite clay (Mnt) exchanged with metal ions (Mnt-M2+, M2+ = Fe2+, Co2+, Cu2+, Ca2+, and Mg2+) over a range of concentration (7.0 × 10-5 M to 12.0 × 10-5 M) and pH (4.... ...
