Testing Beads' filtration ability - Heavy Metals

1. Preparation of solution for 20 ppm concentration


Preparation of Stock Solution

1. ZnCl2 - 120 ppm

  • 0.00266 g of ZnCl2 in 10 mL
    • 10mL*1L/1000mL*120mg Zn/1L*138.315 g/mol ZnCl2/65.38 g/mol Zn = 2.66 mg ZnCl2
    • Mass meassured:

2. CuCl2 - 100 ppm

  • 0.00212 g of CuCl2 in 10 mL
    • 10mL*1L/1000mL*100mg Cu/1L*134.45 g/mol CuCl2/63.54 g/mol Cu = 2.116 mg CuCl2
    • Mass meassured: 0.0022 g

3. Pb(Ac)2 - 100 ppm

  • 0.00157 g of PbAc2 in 10 mL
    • 10mL*1L/1000mL*100mg Pb/1L*325.29 g/mol PbAc/207.2 g/mol Cu = 1.57 mg PbAc2
    • Mass meassured: 0.0016 g
