Optimizing Available Phosphorus in Calcareous Soils Fertilized with Diammonium Phosphate and Phosphoric Acid Using Freundlich Adsorption Isotherm

open access: yesThe Scientific World Journal, 2013
In calcareous soils, phosphorus (P) retention and immobilization take place due to precipitation and adsorption. Since soil pH is considered a major soil variable affecting the P sorption, an acidic P fertilizer could result in low P adsorption compared

Valorization of Pretreated Salvinia molesta Biomass for Ciprofloxacin Biosorption: Kinetic Performance, pH‐Dependent Mechanisms, and Circular Economy Implications

open access: yesWater Environment Research, Volume 98, Issue 2, February 2026.
Powdered Salvinia molesta biomass efficiently removed ciprofloxacin under environmentally relevant conditions, with optimal sorption at a near‐neutral pH. This study highlights invasive plant biomass valorization as a low‐cost circular solution for decentralized water treatment.

Freundlich adsorption isotherms for chromium (III) in Oxisols

open access: yes, 2001
Os impactos causados no ambiente pela aplicação de resíduos de curtume contendo crômio em solos agrícolas devem ser estudados detalhadamente para que se evite a contaminação da biota e das águas subterrâneas. A adsorção do crômio ao solo reveste-se de especial importância em estudos de movimentação de solutos, uma vez que, se a capacidade adsortiva de ...
