Abstract:
... Citrate (Ct) was chosen as a typical chelator used in the Fe²⁺−peroxydisulfate (PDS) process to improve sludge dewaterability. The PDS−Fe²⁺−Ct process exhibited better performance in sludge dewatering than PDS−Fe²⁺. Specifically, with a PDS dosage of 1.2mmol/g VS, the molar ratio of PDS/Fe²⁺ and Ct/Fe²⁺ were 4:5 and 1:4, respectively, the capillary suction time decreased from 155.8 to 24.8sec, and ...

Abstract:
... A colloidal silver nanoparticle (AgNP)-based lateral flow immunoassay (LFIA) was evaluated in terms of the rapid detection of profenofos (PEO) pesticide residue in vegetables. Colloidal AgNPs, of a diameter of approximately 20 nm, were surface-modified with trisodium citrate dehydrate (TSC) in order to improve their stability and dispersion. An anti-profenofos polyclonal antibody (pAb) was success ...

Abstract:
... Bioreduction of soluble U(VI) to sparingly soluble U(IV) solids was proposed as a remediation method for uranium contamination. Therefore, the stability and longevity of biogenic U(IV) are critical to the success of uranium remediation. However, co-occurrence of clay minerals and organic ligands could potentially reoxidize U(IV) to U(VI). Herein, we report a combined effect of Fe(III)-rich nontron ...
