Compost Quality Assessment of Various Agricultural Wastes and Organic Manures

(Corresponding) Radwan S., (Corresponding) Ashour E.
Topic: 
Solid waste management
Today the quality of compost is the most essential criterion in recycling organic wastes, as well as its marketing and utilization in agriculture. Environmentally safe recycling of organic waste to agricultural land could be crucial to sustaining soil productivity in Mediterranean areas, where soil...Read more

One-step Synthesis of TiO2/ZnO Nanocomposites by Refluxing Methods for Photochemical Degradation of Humic Acid

(Corresponding) Fadillah G., HIdayat R., (Corresponding) Wahyuningsih S.
Topic: 
Nanomaterials in the environmnents applications and effects
Synthesis of TiO2/ZnO nanocomposites (TZN) through one-step refluxing method for photochemical degradation of humic acid (HA) in aqueous solution has been studied. Titanium isopropoxide (TTIP) and ZnSO4.7H2O were used as a starting material under base solution at 120 oC for 24 hours. TZN materials...Read more

Analysis of degradation of the micropollutant amoxicillin by photolysis and evaluation of the degradation products

(Corresponding) Hoehne L., Vettorello G., Ethur E., Kuhn D., Freitas E., Steffens C.
Topic: 
Emerging pollutants
Emerging micro pollutants are substances that have recently been identified in environmental matrices, of which information on environmental permanence and toxicity is still scarce. Because of their chemical structure, antibiotics are more stable and require more complex processes for degradation...Read more

Evaluation of Photocatalytic Materials for Water Purification: Overview of the New CEN Standard Test

Triantis T., Kaloudis T., (Corresponding) Hiskia A.
Topic: 
Water treatment
TiO2 photocatalysis offers an attractive alternative to conventional water treatment technologies leading directly to the degradation of organic pollutants, compared to transferring them from one phase to another as in the case of membranes or activated carbon. There is an increasing interest on...Read more
