General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Method of preparing high-purity humic acid[Reference: WebLink]

CN20071097274 on 2007-04-29

Humic acid of high purity is used for the cathode plate expanders of lead storage battery, and also important materials of organic polymer synthesis. This invention relates to a method of extracting and purifying humic acid from low-grade coal. The process is divided into four steps: (1) using alk solution to extract humic acid from coal, adding flocculant, centrifuging to remove dregs to get Humic acid sodium salt, (2) under the meta acidity condition, adding complexing agent to remove high cation, (3) after acidification, using electrodialysis method to elute mineral salts and soluble in the colloidal system, (4) after drying, getting the humic acid powder with purity more than or equal to 95%.

Strengthening Effects of Sodium Salts on Washing Kerosene Contaminated Soil with Surfactants[Pubmed: 26314139]

Huan Jing Ke Xue. 2015 May;36(5):1849-55.


METHODS AND RESULTS:
The impact of sodium salt on kerosene contaminated soil washing with surfactants was investigated. The results indicated that sodium silicate greatly enhanced the washing efficiency of SDS. Sodium tartrate can largely enhance the washing efficiency of SDBS and Brij35. Sodium salts can enhance the washing efficiency on kerosene contaminated with TX-100. No significant differences were observed between different sodium salts. Sodium salt of humic acid (Humic acid sodium salt) and sodium silicate had similar enhancement on kerosene contaminated soil washing with saponin. Sodium humate can be a better choice since its application can also improve soil quality. The enhancement of sodium silicate on kerosene contaminated soil washing with Tw-80 increased with the increase of Tw-80 dosage. However, the impact of sodium chloride and sodium tartrate was opposite to sodium silicate. Sodium salts can reduce surface tension and critical micelle concentration of ionic surfactants to enhance the washing. Sodium salts can also reduce re-adsorption of oil to soil with nonionic surfactants to enhance the washing. Kerosene contamination can increase the contact angle of soil, which indicated the increase of hydrophilicity of soil.
CONCLUSIONS:
Washing with surfactants can reduce the hydrophilicitiy of soil according to contact angle measurement, which indicated that kerosene contaminated soil remediation with surfactant can also benefit nutrient and water transportation in the contaminated soil.

Laboratory and modelling study of the hygroscopic properties of two model humic acid aerosol particles[Reference: WebLink]

The measured mass growth factors of Sigma-Aldrich Humic acid sodium salt (NaHA) and leonardite humic acid (LHA) at 90% relative humidity are 1.87±0.02 and 1.20±0.05, respectively.
METHODS AND RESULTS:
There is a general agreement between the results described in this study with previous TDMA results, which are undertaken with smaller particle ensembles and shorter aerosol–water equilibration times. The measured mass growth factors of Sigma-Aldrich Humic acid sodium salt (NaHA) and leonardite humic acid (LHA) at 90% relative humidity are 1.87±0.05 and 1.20±0.05, respectively.
