Article Synopsis
- A novel electroanalytical method was developed to determine the concentrations of copper (Cu), lead (Pb), and cadmium (Cd) both individually and simultaneously using cyclic voltammetry and square wave voltammetry (SWV).
- The method utilized a modified pencil lead electrode functionalized with a Schiff base, specifically 4-((2-hydroxy-5-((4-nitrophenyl)diazenyl)benzylidene)amino)benzoic acid (HDBA), in a 0.1 M tris-HCl buffer solution.
- Various factors like scan rate and pH were optimized, revealing linear relationships at certain concentrations, confirming the method's accuracy, selectivity, and speed in detecting these
Introduction: The protozoan parasite Cryptosporidium is one of the principal reasons for childhood diarrhea around the world. This work aimed to differentiate Cryptosporidium species among children suffering from diarrhea in Sharkyia Governorate, Egypt.
Methodology: A total of 97 fecal specimens were taken from children suffering from diarrhea, attending Pediatric Clinics of Zagazig University and Al-Ahrar Hospitals.
