Determing Effective Zinc in Soil of Planting Features Fruit and Vegetable in Anning River Basin with Atomic Absorption Spectrophotometry

JIAO Yu;Xichang College;  
Zinc is one of micro nutrition elements that plant needs. To investigate effective zinc in soil of planting features fruit and vegetable in Anning river basin, the zinc contents were determined with atomic absorption spectrophotometry to explore the best conditions and provide data basis for future zinc determination. The results showed that 100 mL HCl + H2SO4(3∶1) mixed acid in 50 ℃ under 6 h after leaching was optimal for atomic absorption spectrophotometer to measure effective zinc content(5.892 ug / g). Relative deviation was 1.34%. The labeled recovery was 97.3%~104.5%. This method was accurate, simple, and convenient.
