ANALYSIS
DETERMINATION OF POTASSIUM AND MAGNESIUM
Why we need potassium and magnesium?
POTASSIUM - provide the ionic environment for metabolic
process in cytosol.(growth regulation)
- potassium ions (K+) for protein synthesis and
opening and closing of stomata.
MAGNESIUM - part of chlorophyll in plant for photosynthesis
METHOD
 Method for the determination of magnesium
Determination of water-soluble magnesium content (MgO)
 Principle
Magnesium in magnesium sulphate fertilizers is extracted in
boiling water and the magnesium content determined by atomic
absorption spectrophotometer.
 Reference: MS 417: Part 6: 1994
PROCEDURE
•Sample preparation
-registration
-drying
-grinding
•Weigh the sample
•Add distilled water and HCl
 Digest the solution using hot plate at boiling point
around 20minutes
 Leave to cool
 Transfer into volumetric flask and dilute to the mark
(250ml)
 Mixed the solution and filter in plastic vial
 Further dilution(100ml)
 Add strontium nitrate(5ml) and dilute to the mark
 To remove phosphate from magnesium and calcium and
prevent interference from other elements
 Preparation for Atomic Absorption Spectrophotometer
 Standard stock solution
- Potassium dihydrogen sulphate solution
- Magnesium sulphate solution
 For 1000ppm,weigh 4.3928g.
 Dry in oven for 2 hours
 Undergo further dilution(m1v1=m2v2)
 0, 0.25, 0.5, 0.75, 1.00 and 1.25 ppm
 Pre-calibrate the AAS with standard stock
solution
 Run the AAS
 Then, we can determine the concentration
of the solution
DETERMINATION OF PHOSPHORUS
Why phosphorus important to plant?
• Essential to stimulate early plant growth and hastens the maturity.
• Development of root health.
• Classified as macronutrient.
Methodology:
• molybdovanadate method (yellow method).
Reference:
•MS 417: Part 4: 1994
Apparatus:
Spectrophotometer.
Principle:
•Amount of light transmitted (yellow colour) dependent on the
concentration of phosphorus.
•Spectophotometric absorption curve from known standard
phosphorus solutions determined in unknown solution.
Standard stock solution:
 Potassium dihydrogen phosphate (4.3928g in 1L)
 1000ppm 100ppm
 (0ppm 2ppm 4ppm 8ppm 10ppm)
Reagent used:
 Molybdovanadate reagent: Ammonium molybdate (100ml) mixed
together with ammonium
vanadate (150ml).
Aqua regia:
 Mixing the HCl & HNO3 together.
PROCEDURE
 Sample preparation and
weigh the samples (fertilizer)
 Add distilled water.
 Add 10ml HCl and 5ml HNO3 and boil.
 transfer into volumetric flask.
 Mark-up with distilled water then filter.
 1ml of sample solution is pipette into 100ml volumetric
flask.
 Add Molybdovanadate reagent and diluted to the mark
with distilled water.
 prepare calibration standard (0,2,4,6 & 8 ppm) from the
stock solution (1000ppm) and take reading after 30
minutes.
 Determine phosphate at acidic colour at pH ± 2.6
 Double acid method is used.
 We put HCl and HNO3 to convert all polyphosphate (P2O7) to
orthophosphate (PO4
3-).
 phosphate + metavanadate = phosphomolybdate acid + water.
(yellow colour)
INSTRUMENT:
INDUCTIVELY
COUPLED PLASMA
(ICP)
INTRODUCTION
INDUCTIVE COUPLED PLASMA (ICP)
 measures the light emitted at element-specific characteristic
wavelengths from thermally excited analyte ions .
 light emitted is separated and measured in a spectrometer, yielding
an intensity measurement that can be converted to an elemental
concentration by comparison with calibration standards.
Mass spectrometry (MS)
 2 type - determination for element
having unit PPB-PPT
Optical Emission Spectrometry
(OES)
- determination for element
having unit PPM-PPB
 Gas used:
 helium and argon
 Calibration- Manganese
Radial – 10PPM
axial- 1PPM
PART OF MACHINE
AND
HOW IT WORK
1. COMPUTER
2. SAMPLER
3. PUMP
4. CHAMBER
5. NEBULIZER
6. FLAME INJECTION
7. TORCH
8. AXIAL / RADIAL
9. SPECTRUM
 Selection of colour for each element.
 Convert into energy Eo
 Transfer into computer- calculate intensity, log10 = 1/Eo
 Can analyze 43 element in the periodic table except for nitrogen and
oxygen
 Eg: Phosphorus P, Potassium K, Sodium Na,
Boron B, Calcium Ca, and etc.
 Error of ICP : 0.05%
CALCULATION
 Run standard
P, K, Mg, B
 Plot graph.
 From graph, calculate slope, m
 Formula, y=mx + c
 Calculate intensity
 Calculate ppm, formula
PPM= (intensity-intercept)/slope
