WebAnalyses were performed each month on different samples of a batch, stored at 4, 23, 30 and 37 degrees C. No significant (P greater than 0.1) variations occurred in potency, protein and phenol concentrations, pH, sterility or safety, at any of the storage temperatures during the study period. WebThen, 1 mL of ginseng extract was mixed with 1 mL of 5% phenol and 5 mL of concentrated sulfuric acid, and this sample was put in a water bath at 100 °C and allowed to react for 20 min. After the reaction time was reached, it was quickly cooled to room temperature with an ice-water bath, and the absorbance of the samples was measured with a …

Web29 Jun 2024 · Carbolic acid is an aromatic organic compound in the form of a volatile white crystalline solid. It is mildly acidic and requires careful handling because it can cause chemical burns. Originally extracted from coal tar, carbolic acid is today produced on a large scale (around 7B kilograms per year) from petroleum-derived feedstocks. Web6 Aug 2011 · The equilibrium adsorption of phenol from aqueous solution was determined as follows: carbon foam (0.1 g) was added to each of a series of solutions of phenol (50 mL) with varying concentrations from 0.8 to 3.0 mmol/L. The bottles were sealed with paraffin film and then shaken at 298 K at a frequency of 100 strokes min −1 for 24 h. hilbert indo hasudungan
