Objective To study the purification process of the water extract of Phellodendron by different methods.Methods Using the content of berberine hydrochloride and dry extract rate as investigation index,and using HPLC fingerprint to optimize the optimum method in centrifugation,chitosan flocculation sedimentation...
Using as examples water bodies in different geographical zones (Lake Ladoga, the River Sukhona, shallow-water ponds of the North Caucasus) the known methods of water quality evaluation by means of oligochaetes are considered. There is no unique universal method of pollution bioindication in this ...
For water purification treatment various technologies are in use. There are two main approaches to water pollutions removal. First approach relies on the use of cheap adsorbents [2], [3] and second one employs photocatalysts like titanium dioxide. In 2001, Asahi et al. [4] prepared nitrogen ...

In the latter, gas is introduced into the water vortex, and the formed gas bubbles are broken into microbubbles by breaking the vortex (Fig. 1B) (Takahashi, 2009). No comparative studies exist on the effects of OMB generated by different methods on the removal of residual pesticides in ...
Results showed that the MSPD technique could effectively mitigate matrix interference, but its recoveries of PSTs were significantly lower than those of the HCl and AcOH extraction methods followed by carbon SPE purification. The molar concentrations of M-toxins obtained by the MSPD method were ...
