Quantitative chemical analysis showed the presence of trace quantities of some inorganic elements along with phosphorous in TNP. The experimental adsorption data fitted reasonably well to both Freundlich and Langmuir isotherm. pHzpc of TNP was 5.1, which indicated that the adsorbent was more potential for cationic adsorption. The adsorption kinetic data followed a pseudo-second order model for zinc. Optimum Zn2+ loading was 9.20 mg/g for 10.31 mg/l initial zinc concentration at pH 5.80. Zn2+ loading on TNP was dependent on initial zinc concentration. TNP was a potential adsorbent for the removal of Zn from the effluent of electroplating industry. (c) 2007 Elsevier Ltd.

The unparalleled selectivity that it offers over other alternatives combined with the considerable robustness and scalability make it the unit operation of choice in downstream processing. It is typical to have three to five chromatography steps in a purification process for a biotherapeutic. Generally, these steps offer different modes of separation such as ion-exchange, reversed phase, size exclusion, and hydrophobic interaction. In the past decade, multimodal chromatography has emerged as an alternative to the traditional modes. It involves use of more than one mode of separation and typically combines ion-exchange and hydrophobic interactions to achieve selectivity and sensitivity. Over the last decade, numerous authors have demonstrated the significant potential that multimode chromatography offers as a protein purification tool. This review aims to present key recent developments that have occurred on this topic together with a perspective on future applications of multimodal chromatography.1 aHalan, V.1 aMaity, S.1 aBhambure, R.1 aRathore, A., S.  uhttps://library.ncl.res.in/content/multimodal-chromatography-purification-biotherapeutics-review
