V. Equipment required:
• Hanna HI 5315 Double Junction Reference Electrode
with HI 7072 Fill Solution for use with HI 4015.
• Hanna HI 4222 pH/ISE/mV meter or other suitable
ion or pH/mV meter. (Note: log/linear graph paper is
useful if an ISE (ion) meter is not available).
• Hanna HI 180 Magnetic Stirrer or equivalent with
Teflon coated stirring bars (HI 731320). (Note: iso-
late beakers from stirrer motor heat by placing insu-
lating material such as foam or cork between them).
• Hanna HI 76404 Electrode Holder or equivalent.
• Plastic beakers (HI 740036P) or other suitable mea-
surement vessel.

Solutions Required for Calibration
Select appropriate Hanna Instruments standard and ISA
from the list below:
0.1 M Silver Standard, 500 mL HI 4015-01
ISA for Silver measurement, 500 mL HI 4000-00
SAOB for Sulfide measurement, 500 mL HI 4015-00
Note: For Sulfide standard, see directions that follow.
Silver Standards
For Molar solutions:
Using volumetric pipettes and glassware make serial dilu-
tions of HI 4015-01 to approximately bracket the concen-
tration of the samples. Standards with concentrations
< 10
-3
M should be prepared daily. Store in dark plastic
bottles.
Two mL of Hanna ISA for Halide electrodes (HI 4000-00)
should be added to 100 mL of sample or standard.
For ppm solutions:
Prepare 1078.7 ppm Silver standard by diluting HI 4015-
01: Pipette 100 mL standard to a 1 liter volumetric flask.
Add deionized water to volume. Using additional pipettes
and glassware make serial dilutions of this 1078.7 ppm
standard to bracket the sample concentra-
