| titleOfInvention | The pre-treating method of sea-tangle determining heavy metals |
| abstract | The present invention relates to the pre-treating method of a main laminaria determining heavy metals, step is as follows：（1）Sea-tangle to be measured is dried, is crushed, and cross 40 mesh sieves；（2）Weigh 0.2g Kelp Powders to be placed in high-pressure digestion tank, add 65% nitric acid, stand 1-2h；（3）Counteracting tank is put into microwave dissolver, the peak power 800W of microwave dissolver, climbing time 5min, 120 DEG C of temperature keeps 3min；（4）The peak power 800W of microwave dissolver is set, and climb time 6min, 164 DEG C of temperature keeps 15min；（5）After the completion of clearing up, less than 40 DEG C are cooled to, take out counteracting tank；（6）Digestion solution is transferred in volumetric flask, with ultra-pure water constant volume, shake up, stand overnight it is to be measured.The processing method time of the invention is shorter, simple to operate, save the consumption of the reagents such as inorganic acid, and more thorough to clearing up for sample. |
